The document discusses the major habitat types of the Indian subcontinent. It defines habitat as the place where an organism lives. There are three main types of habitats: terrestrial habitats including grasslands and deserts where organisms live on land, aquatic habitats including lakes, rivers, and oceans for organisms that live in water, and aerial habitats of the sky used by flying organisms like birds and insects. Each habitat provides living and nonliving components for the organisms that reside within them.

1.Generally speaking, adaptive radiations occur when new, unoccupied ecological niches become accessible to a founder population.
This can happen after a mass extinction during which the previous occupiers of those niches died out.
t can also happen when a colonizing species arrives at an island. (For instance the ancestor of the honeycreepers in Hawaii, or of Darwin's "finches" in the Galapagos)
Honey creeper
Change feeding habitat
At least 56 species of Hawaiian honeycreepers known to have existed, although all but 18 of them are now extinct.
Lack of competition. When a species enters an adaptive zone, it is poorly equipped to compete with species that have become adapted to the same niche.
For example, mudskippers are fish that are making a living on land, but they are marine fish and they don't have to compete against frogs and salamanders, which are restricted to fresh water. That is why we don't see freshwater mudskippers.

- Synapsid skulls, seen in early mammal-like reptiles
Aquatic adaptations
Introduction:
Adaptation to environment is one of the basic characteristics of the living organisms. Living organisms are plastic and posses the inherent properties to respond to a particular environment.
It is a facet of evolution and involve structural diversities amongst living organisms that are heritable. Organisms exhibit numerous structural and functional adaptations that help them to survive as species and to overcome the tremendous competition in nature.
All classes of vertebrates have their representatives leading to partial or total aquatic life.
Water is a homogenous medium for animals.
As a medium, it is heavy in concentration than air.
Stable gaseous and osmotic concentration in a specific region.
Temperature fluctuation is minimum for a particular region.
Water bodies generally have very rich food resources.
Characters of an Aquatic Animal:
An aquatic animal should have the ability to swim to overcome the resistance of the surrounding medium.
Therefore, it should have a streamlined body with an organ or ability to float.
The animal should also have to overยญcome the problem of osmoregulation.
There are two types of animals living in the present day water, which have undergone aquatic adaptation.
According to their origin, they are primary and secondary aquatic animals.
Adaptations to water habitat are of two types:
Primary aquatic adaptations which includes primitive gill-breathing vertebrates (fishes); Those aniยญmals, whose ancestors and themselves are living in the water from the very beginning of their evolution, are called primary aquatic animals. In other words, primary aquatic animals never had a terrestrial ancestry. They exhibit perfect aquatic adaptations. All fishes are primary aquatic animals.
Secondary aquatic adaptations which are acquired as in reptiles, birds and mammals. Those aniยญmals whose ancestors were lung breathing land animals, migrated to the water for some reason and ultimately got adapted to live in aquatic habitat, are called secondary aquatic animals. Some of them live partially while others live totally in the water. All aquatic reptiles, aves and mammals are represenยญtatives of secondary aquatic animals. Amphibians are in a transitional form between primary and secondary aquatic life.
Sensory adaptations like, electroreception for electrolocation and electro communication, olfaction (vomeronasal system), balance (spatial orientation, movement perception), vision (cornea curvature, retinal topography), and hearing (acoustics, ear anatomy) under the underwater sound reception mechanisms in various aquatic amniotes are well developed.
Proximate vs ultimate causes of animal behavior
Two broad categories of behaviors are Proximate and Ultimate behaviour. The presentation gives a brief introduction on Proximate and Ultimate causes of behaviour
Animal behavior
Animal behavior types can be categorized into several types including learning, habituation, imprinting, classical conditioning, trial and error learning, latent learning, insight, reasoning, and cognition. Learning is the modification of behavior based on experiences and can range from simple to complex. Habituation is the decrease in response to repeated stimuli over time. Imprinting occurs during a sensitive period where young animals learn recognition and attraction patterns. Classical conditioning pairs an innate response with a new stimulus. Trial and error and insight involve solving problems through testing or understanding relationships. Latent learning occurs without reinforcement. Animal cognition allows perception, processing, and use of information.
Metapopulation
A metapopulation is a widely used concept in Ecology and Evolution. It is responsible for the stability of a population in an area.

Ecological niche
An ecological niche describes how a species interacts with and fits into its environment, including obtaining resources like food and shelter, and reproducing. A niche encompasses all biotic (living) and abiotic (non-living) factors. The fundamental niche is the full range of environmental conditions a species can tolerate without competition from other species. Species niches depend on factors like temperature, resources, and predators. Niches can overlap if species partition resources in non-competing ways, like dolphins and seals eating different types of fish.
Metamorphosis-amphibians, hormonal control
Metamorphosis in amphibians involves dramatic changes initiated by thyroid hormones that transform aquatic larvae into terrestrial adults. These changes include remodeling of tissues and organs like development of lungs and loss of gills to transition from aquatic to terrestrial respiration. Changes in skin, digestive system and other organs prepare the amphibian for life on land. The process is controlled by thyroid hormones which activate receptors that turn on genes driving tissue remodeling and metamorphosis.
Ecological niche
Ecological niche refers to an organism's role and position in its environment, including where it finds food and shelter and what environmental conditions it requires. An organism's niche is influenced by biotic factors like availability of food and predators as well as abiotic factors like temperature, soil nutrients, and light levels. Earthworms are an example of niche construction, as they physically and chemically modify soil in a way that allows them to survive on land. Niches can be fundamental, representing all possible resources an organism could use, or realized, reflecting the niche an organism actually occupies due to competition. The competitive exclusion principle states that two species with identical niches cannot coexist long-term. Resource partitioning allows similar species to co
Evolutionary significance of dipnoi
The document discusses the evolutionary significance of lungfish (Dipnoi) and whether they are the ancestors of amphibians. It describes the distribution, primitive characters, and specialized characters of modern lungfish. It then analyzes the affinities of lungfish with other fish groups like sharks, holostean fish, ray-finned fish, and crossopterygian fish, noting both similarities and differences. While lungfish share some characteristics with amphibians like pulmonary respiration and egg-laying, they also have key differences. The conclusion is that lungfish are not a direct ancestor of amphibians but are more likely a specialized offshoot that shared a common ancestor with early amphibians and crossopterygian
Benefits Of Wildlife
There are four main benefits that wildlife provides to humans: economic, medical/scientific, aesthetic/recreational, and ecological. Economically, wildlife benefits humans through industries like hunting, fishing, and wildlife watching, which together amount to over $18 billion annually in the US. Medicinally, plants have provided medicine for 80% of the world's population and make up about 40% of all medicines. Aesthetically, wildlife viewing motivates recreational activities and ecotourism. Ecologically, all living things interact within ecosystems, so impacts to one species can affect many others.
Origin and evolution of ostracoderms
Ostracoderms were early jawless vertebrates that lived from the Cambrian to the late Devonian period. They were covered in bony plates and resembled modern hagfish and lampreys. While some evidence suggests they lived in freshwater, their habitat is still debated. Later in the Devonian, jawed fish evolved from ostracoderms and outcompeted them, contributing to their extinction by the end of the period. Ostracoderms were divided into two main groups and played an important role in the early evolution of vertebrates.
Oriental region fauna
This document provides information on the geographical limits, climatic conditions, and characteristic fauna of the Oriental biogeographic region. It notes that the region includes India, Southeast Asia, and southern China. The climate varies from temperate in northern India to tropical rainforests in eastern parts. Common fauna include carps and catfishes in waters, frogs and salamanders on land, and a diversity of reptiles including lizards, snakes, and turtles. A wide variety of bird families are found across the region. Mammals include rabbits, squirrels, monkeys, elephants, and several endemic families.
Island biogeography
This document discusses island biogeography and provides examples of continental and oceanic islands. It describes how continental islands like Great Britain and Borneo have fauna more similar to nearby mainland areas due to past connections, while oceanic islands have fauna that arrived by air/water and is often endemic. It discusses species-area relationships and how larger islands support more species due to lower extinction rates. It summarizes Robert MacArthur and E.O. Wilson's equilibrium theory of island biogeography.
R and k selection.
R-selection refers to species that live in unstable environments and produce many cheap offspring, while K-selection refers to species that live in stable environments and produce few expensive offspring. Key differences are that r-selected species have highly variable populations with early reproduction and many offspring, while K-selected species have small populations with a higher risk of inbreeding and later reproduction after parental care. Characteristics of r-strategists include small size, low energy per offspring, short lifespan and multiple reproduction, while K-strategists have the opposite traits. The terms r and k come from the logistic growth equation.
r and k selection
This document discusses r and K selection theory, which seeks to explain how traits evolve in response to environmental variation and mortality. It examines how traits are interrelated and constrained by ecology. R and K selection theory predicts demographic responses to disturbances at different spatial and temporal scales. The most notable example is MacArthur and Wilson's theory of r and K selection based on island biogeography. R-selected species thrive in variable environments and have high fecundity, while K-selected species exist in stable environments and invest more in parental care and fewer offspring. The r and K classification represents ends of a continuum, with most species falling somewhere in between.
Filter feeding of molluscs
Unio is a type of mollusc that feeds by filtering particles from water. It draws water in through its incurrent siphon using cilia, which beat to transport food like diatoms, protozoa, and detritus towards its mouth. Larger particles are trapped in mucus on its gill surfaces and conveyed to the mantle cavity while smaller particles are moved to the mouth to ingest. This filter feeding process involves the coordinated beating of cilia to efficiently collect and sort food from large volumes of circulating water.
Mate selection (Mating systems)
This document discusses mate selection strategies in animals. It defines sexual selection as selection arising through variation in mating success, and distinguishes between intra-sexual selection through male-male competition and inter-sexual selection through female choice of males. Different mating systems like monogamy, polygyny, and promiscuity influence the strength of sexual selection and variance in male mating success. Specific mate selection strategies discussed include harem defense polygyny, where males defend territories containing multiple females; lekking polygyny, where males aggregate and compete on leks to display for females; and polyandry in some jacana species, where females mate with and leave eggs with multiple males.
Parental care in mammals
Parental care involves investment from parents to increase offspring survival and fitness. In mammals, most care is maternal, involving lactation. Only 6% of mammals show biparental care where monogamous males and females provide care. Paternal care can involve protecting young from predators and helping with growth. For artiodactyls like deer and antelopes, females are the sole caregivers through lactation. They use hiding or following strategies to protect vulnerable young until independent.

Origin and evolution of reptiles
The document summarizes the evolution and history of reptiles. It states that reptiles arose from amphibians around 350 million years ago during the Carboniferous period. The earliest reptiles were small insect-eating lizards. Reptiles then diversified and became the dominant land vertebrates by the Permian period. During the Mesozoic era, various reptile groups flourished, especially dinosaurs which appeared in a wide variety of forms. However, most dinosaurs went extinct around 65 million years ago at the end of the Cretaceous period, likely due to an asteroid impact that caused climate change. Despite this mass extinction, modern reptile orders like turtles, lizards, snakes and crocodiles survived
FATE Map
A chart showing the fate of each part of an early embryo, in a particular blastula stage is called fate maps. It is done because the correct interpretation of gastrulation is impossible without the knowledge of the position which are the presumptive germinal layers (Ectoderm, Mesoderm and Endoderm) occupy in blastula.
Fate mapping is a method used in developmental biology to study the embryonic origin of various adult tissues and structures. The "fate" of each cell or group of cells is mapped onto the embryo, showing which parts of the embryo will develop into which tissue. When carried out at single-cell resolution, this process is called cell lineage tracing. It is also used to trace the development of tumors.
Taxonomic publication
One major challenge is the time consumed by the interplay between the taxonomist and the publisher in preparing taxonomic data and going to print. Breaking this bottleneck requires seamless integration between compilation of the descriptive taxonomic data and the publication upon which the data are based
ICZN.pptx
The document discusses the International Code of Zoological Nomenclature (ICZN) which provides rules for formally naming animal species. It is published by the International Commission on Zoological Nomenclature and aims to ensure every animal has a unique and universally accepted scientific name. The ICZN has six main principles including binomial nomenclature, priority, coordination, and typification to determine the correct scientific name of animal taxa. It also outlines how names are structured at different taxonomic ranks from species to orders.
Navigation in birds
This document summarizes navigation and migration in birds. It discusses that birds migrate seasonally between breeding and wintering grounds. Long-distance migrants like the Blackpoll Warbler travel between Canada and Central/South America while short-distance migrants make shorter trips. Migratory journeys are broken into short flights covering 300-600km per night over 3-4 weeks. Birds use various cues and mechanisms for navigation including landmarks, the sun, stars, and the earth's magnetic field. Food availability also influences migratory patterns as insect-eating birds follow insect populations south in winter.
Habitat of the living
This document provides information about different types of habitats and ecosystems. It discusses forests, tropical forests, temperate forests, boreal forests, grasslands, deserts, mountains, polar regions, aquatic habitats, freshwater habitats, marine habitats, coastal habitats, estuaries, coral reefs, and how plants and animals adapt to their environments. Pictures are included to illustrate each habitat type. The document also covers animal adaptations like camouflage, migration, hibernation, and how plants and animals depend on each other.
Ecosystems
Aquatic ecosystems include freshwater ecosystems like lakes, ponds, rivers and streams, as well as marine ecosystems like oceans, estuaries and coral reefs. Terrestrial ecosystems include forest ecosystems like coniferous, deciduous and rainforests, as well as tundra, desert and grassland ecosystems. Mixed ecosystems combine aquatic and terrestrial elements, such as wetlands that flood seasonally and coastlines where land meets the sea.

Scienceprojectwork
This document discusses different habitats and the animals that live in them. It begins by describing grasslands, noting that they lack trees and have an open landscape, making them home to large herding animals. It then discusses aquatic habitats, describing the variety of salinity levels and currents found in different aquatic environments. The document defines aquatic habitat and explains how fish rely on specific habitats to survive and complete their lifecycles. It also describes mountain region habitats, noting the cold temperatures and thick fur of animals there. Finally, it discusses desert habitats and the adaptations animals have, like camels' ability to go long periods without water, to survive the extreme heat and lack of water in deserts.
Habitat .pdf
Habitat refers to the natural environment where an organism lives and provides everything it needs to survive, including food, shelter, and mates. There are three main types of habitat: freshwater, marine, and coastal. Freshwater habitats include rivers, lakes, and streams, while marine habitats are the oceans and seas. Coastal habitats are where land and sea meet. Major habitats include forests, grasslands, deserts, mountains, polar regions, and aquatic habitats. Habitat can be affected by both natural changes like fires or drought as well as human-caused changes like habitat loss.
Ecosystems and food webs by mondlane.j
This document describes different ecosystems and their key characteristics. It discusses mountain, sea, rocky shore, grassland, forest, river, and wetland ecosystems. Each ecosystem is defined by its abiotic factors like temperature, water, sunlight, and soil composition as well as its common plant and animal species that are adapted to those conditions. The document also introduces food webs, explaining that in an ecosystem living things like plants, animals, and microbes interact and depend on non-living things like air, water, sunlight, and soil. Classwork examples are provided to analyze and illustrate ecosystem components like dominant plants and animals, available resources, and feeding relationships between organisms.

Class work examples are provided, such as drawing plants and animals from an ecosystem and constructing simple food webs that illustrate feeding relationships.
HABITAT.pptx
The document discusses different types of habitats including aquatic, terrestrial, and arboreal habitats. It provides examples of organisms found in each habitat and describes their adaptations. Aquatic habitats include freshwater, marine, and estuarine environments inhabited by organisms like whales, turtles, and water plants. Terrestrial habitats refer to land environments where organisms such as humans, domestic animals, and wild animals live. Arboreal habitats refer to life in or on trees and are home to animals like parrots and monkeys. The document then discusses examples of adaptations that allow organisms to survive in their habitats, such as gills and fins in aquatic organisms, extensive root systems in terrestrial plants, and wings in arboreal birds and bats.
The biosphere and animal distribution
animal distribution is directly related with the environmental changes. These changes affect the over all life cycle of the animal. This further leads to adaptation in the organisum
Lake Community, Sea Community and the Different types of forest
Lentic ecosystems like lakes have both biotic elements like plants and animals as well as abiotic factors involving physical and chemical interactions. They differ from lotic ecosystems like rivers that involve flowing water. Together they are part of the broader study of freshwater ecology. Marine ecosystems cover over 70% of the Earth and include coastal systems like salt marshes as well as offshore areas like the deep sea. Forests can be classified by latitude into tropical, temperate, and boreal types with distinct characteristics like rainfall and species present in each.
Biomes ecology
The document describes the major biomes found on Earth, including aquatic and terrestrial biomes. It provides details on the defining characteristics, climates, soils, and common plant and animal species found in freshwater, marine, desert, grassland, forest, tundra and other biomes. Biomes are grouped based on whether they are primarily aquatic or terrestrial, and further broken down by specific biome type within those groups.
Biomes ecology
The document describes several major biomes including aquatic and terrestrial biomes. The aquatic biome includes freshwater regions like ponds, lakes, streams, rivers and wetlands as well as marine regions like oceans, coral reefs, and estuaries. Terrestrial biomes described include deserts, chaparral, savannas, temperate grasslands, temperate rain forests, tropical rain forests, temperate deciduous forests, taiga, and tundra. Each biome is characterized by its climate, soil, and dominant plant and animal species.

ecosystem-3.pptx
An ecosystem is a community of living organisms that interact with each other and their non-living environment. Tropical rainforests are dense ecosystems with tall trees and dense canopies that receive high rainfall. They house incredible biodiversity above and below the forest floor. Coral reefs are underwater ecosystems composed of living corals, algae, fish and other marine life that interact with their non-living environment. Mangrove swamps are coastal ecosystems found in tropical and subtropical regions that are home to plants and animals adapted to changing saline conditions, providing important habitat.
FRESH WATER
Fresh water is defined as having a low salt concentration, usually less than 1%. It can be found in ponds and lakes, which absorb heat from the sun and support various plant and animal life. Streams and rivers are bodies of moving water that change in characteristics from source to mouth, with cooler temperatures at the source. Wetlands are very wet areas that support aquatic plants adapted to humid conditions, such as marshes, swamps, and bogs.
ECOSYSTEM -WPS Office.pptx
An ecosystem is a community of living things that interact with each other and their physical environment. It can include plants, animals, fungi, bacteria and other organisms as well as non-living elements like weather and landscape. Ecosystems provide environments for organisms to live and they maintain balance through complex interconnections between living and nonliving components. Examples of ecosystems discussed include deserts, tundra, rainforests, oceans, savannas and swamps.
Habitats of Animals
The document discusses the five main habitats where animals live - forests, deserts, polar regions, oceans, and fresh water. It provides examples of animals that inhabit each habitat and describes adaptations that allow animals to survive in each environment. Forest habitats provide shelter for animals like lions, tigers, deer and foxes. Desert animals have thick skins and store water to endure harsh, dry conditions. Polar region animals live in groups and have insulating fur to withstand cold temperatures. Oceans are home to whales, dolphins, seals and octopuses adapted to salty water. Fresh water habitats shelter fish, frogs, ducks and insects in places like ponds and rivers.
Class 7 Geography chapter no. 01 Environment
The document discusses the environment and its components. It defines environment as the natural and human-made phenomena that surround living organisms. The natural environment includes biotic factors like plants and animals, and abiotic factors like land, water, and air. The human environment comprises human activities and interactions. The environment has four domains - lithosphere, atmosphere, hydrosphere, and biosphere. An ecosystem is the relationship between living organisms and their interaction with the surrounding environment. The human environment involves humans interacting with and modifying the natural environment to meet their needs over time.
nature present.pptx
Nature can be defined as the material world of the Universe and is the main object of study for natural sciences. It includes natural habitats not created by humans. Historically, kingdoms have been used to classify nature, starting with plants, animals, and minerals. Later kingdoms were added for protists, monera, and archaea. Oceans cover most of the Earth's surface and are divided into bodies like the Pacific, Atlantic, Indian, Southern, and Arctic Oceans as well as seas and salt lakes. Ecosystems are composed of biotic and abiotic components that function interdependently, and the human ecosystem concept is based on human dependence on nature. Plants and animals were originally divided by Aristotle and Linna
Animals
This document discusses different types of habitats including deserts, oceans, forests, freshwater, and polar regions. It provides examples of animals that live in each habitat, including desert tortoises, camels, fish, dolphins, lions, giraffes, ducks, frogs, polar bears, and walruses. It also covers different types of animals based on their diets, such as herbivores, carnivores, and omnivores, giving examples like rabbits, deer, lions, tigers, monkeys, and bears. The document discusses camouflage and how different animals use camouflage techniques. It concludes by describing bird migration patterns.
Habitat of the Animals
Animals live in habitats that provide resources for resting, growing, and reproducing, such as trees, gardens, jungles, deserts, bodies of water, and both land and water. A habitat is the natural environment where an animal or plant normally lives and grows. The document discusses different habitats for various animals including those found in gardens, jungles, deserts, water, and animals that can live on both land and in water.

REPLICATION OF VIRUS
Virus replication follows several key stages:
1) Attachment of the virus to receptors on the host cell surface.
2) Penetration of the virus into the host cell.
3) Release of the viral genome from the capsid through uncoating.
4) Synthesis of viral proteins and genome through transcription and translation of the viral genes.
5) Assembly of new viral progeny.
6) Release of progeny viruses from the host cell through lysis or budding, spreading the infection.
BACTERIAL PHOTOSYNTHESIS
Purple sulfur bacteria are a type of photosynthetic bacteria that perform anoxygenic photosynthesis. They contain bacteriochlorophyll which absorbs infrared light and uses hydrogen sulfide as an electron donor, producing sulfur as a byproduct instead of oxygen. There are two main types, Chromatiaceae and Ectothiorhodospiraceae, which differ in where they produce sulfur particles. Purple non-sulfur bacteria are similar but use hydrogen instead of hydrogen sulfide and do not produce sulfur. Green sulfur bacteria also perform anoxygenic photosynthesis but appear greenish in color and can use hydrogen or thiosulfate instead of hydrogen sulfide.

Bacterial transduction (Bacterial genetic recombination)
Transduction is the process by which bacterial viruses called bacteriophages transfer genes between bacteria. There are two types: generalized transduction, where any bacterial DNA can be transferred during the lytic phage cycle, and specialized transduction, where specific DNA near the phage genome is transferred during lysogeny. Transduction was an important tool for early discoveries in genetics and continues to be useful for genetic engineering and gene therapy applications today.
Levels of biodiversity (Plant Biodiversity)
Biodiversity exists at multiple levels - genetic, species, and ecosystem diversity. Genetic diversity refers to variation within and between populations/species. Species diversity looks at the variety and relative abundance of species in a community. Ecosystem diversity considers ecological variation within ecosystems, including trophic levels and interactions between organisms, as well as the variety of ecosystem types in a landscape.
NBPGR-National Bureau of plant genetic Resources.
The National Bureau of Plant Genetic Resources (NBPGR) was established in 1976 in India in response to the effects of the Green Revolution on agrobiodiversity. It plays a pivotal role in improving crops and facilitating crop diversification through germplasm collection and conservation. NBPGR has its headquarters in New Delhi and 10 regional stations located across India's phyto-geographical zones to support its work in exploration, evaluation, and maintenance of plant genetic resources. It draws guidelines from various committees and works to effectively manage plant genetic resources in harmony with international agreements.

fungi: heterothallism, heterokaryosis, parasexuality,fungi sex hormones, Mycorrhizae, Types of mycorrhizae, Defence mechanism in plants- structural and biochemical.
BACTERIA/EUBACTERIA (Microbiology)
Bacteria are microscopic single-celled organisms that can thrive in diverse environments like soil, oceans, and the human gut. They reproduce through binary fission and come in various shapes such as coccus, spiral, and bacillus. Bacteria play both beneficial and harmful roles. Positively, they are important for agriculture, food production, and industry by aiding processes like fermentation and antibiotic production. However, some bacteria can also cause food spoilage, food poisoning, and diseases.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

Major habitat type of sub continent
- 1. Major habitat type of sub- continent NISHA KATARIA
- 2. The place where an organism lives is known as habitat. For example, the habitat of a fish may be a lake, pond, river, sea or other aquatic systems. habitats of cacti and camel are sandy, dry, hot deserts. The habitat of Indian rhinoceros is grassland. Each habitat comprises abiotic or nonliving components and biotic or living components. HABITAT
- 3. Basically the entire world may be divided into three spheres- ๏ถthe atmosphere (air), ๏ถthe lithosphere (land), and ๏ถthe hydrosphere (water). The whole zone of air, land, and water at the surface of the earth occupied by living beings is called biosphere. Types of habitat
- 4. Terrestrial habitat ๏ถ Organisms that live and move on land are called terrestrial organisms. ๏ถ This habitat is not uniform as there are many barriers like deserts, Mountains Rivers, etc., on it. ๏ถ The light factors of terrestrial habitat fluctuate with the season and the altitude. ๏ถ Some common terrestrial organisms are trees, ferns, elephant, camel, man, etc.
- 5. Aquatic Habitat ๏ถ Organisms which live in water are known as aquatic organisms. These organisms live and breed or propagate in water. ๏ถ They are classified as freshwater and marine organisms, ๏ถ Freshwater habitats may be subdivided into lentic (stagnant) and lotic (running) types.
- 6. Aerial habitat ๏ถ The organisms that use air (sky) for their activities are known as aerial (Volant) organisms. ๏ถ bats, birds and insects. ๏ถ There are some organisms which can use both water and terrestrial systems as their habitat. ๏ถ They are called amphibious. ๏ถ Examples are frog and toad.
