This document discusses the importance of environmental studies. It notes that environmental studies will help develop sustainably without destroying the environment, educate people on efficiently using resources, and highlight environmental issues to work on resolving. It also discusses key concepts related to environment and ecology, including defining ecology as the study of organism interactions and their environment. Components of the environment and types of ecosystems are also outlined.
This document discusses environmental concepts like biodegradable and non-biodegradable wastes, food chains, food webs, trophic levels, and ecosystem components. It provides examples and definitions for each. Specifically, it defines biodegradable wastes as those that can be broken down by microorganisms, like cattle dung and compost. Non-biodegradable wastes cannot be broken down, such as plastics, metals, and chemicals like DDT. It also explains that decomposer organisms break down natural materials but not man-made ones.
The nitrogen cycle describes how nitrogen moves between the atmosphere, soil, plants, and animals. Nitrogen makes up most of the air but cannot be used by plants and animals in its atmospheric form. Bacteria play a key role in fixing nitrogen by converting it into forms that can be used by plants through processes like nitrification and assimilation. Humans have disrupted the natural nitrogen cycle through activities like fertilizer use that introduce excess nitrogen. Maintaining the balance of the nitrogen cycle is important for ecosystems and the environment.

Human populations and their environments have a complex relationship. Populations grow exponentially under ideal conditions until reaching carrying capacity, limited by density-dependent factors like disease and competition. While humans have overcome many limits through technology, current population growth is unsustainable and threatens biodiversity through activities like urbanization, deforestation, and pollution. Conservation of resources, pollution control, and restoration of damaged ecosystems are needed to restore environmental health.
1. The document discusses various modes of reproduction in living organisms including asexual reproduction methods like binary fission, budding, spore formation, regeneration, fragmentation, and vegetative propagation.
2. It also describes sexual reproduction which involves the fusion of male and female gametes to form a zygote that develops into a new organism.
3. DNA replication during reproduction is highlighted as essential for transmitting characteristics from parents to offspring, with variations introduced through imperfect replication allowing for evolution of species over time.
The document defines ecology and describes various ecological concepts and components. Ecology is defined as the scientific study of the interactions between organisms and their physical environment. It discusses the components of different ecosystems including producers, consumers, decomposers and their interactions through food chains, food webs and nutrient cycles. Major ecosystem types described are forests, grasslands, deserts, freshwater and marine systems.
The sulfur cycle describes the movement of sulfur through the biosphere and lithosphere. Sulfur is released into the atmosphere through volcanic eruptions, fossil fuel burning, and decaying organic matter. It is then converted to sulfuric acid and deposited back on land and oceans through precipitation. Sulfur is essential for life and cycles between its reduced and oxidized forms as it moves between living and nonliving parts of the Earth system. Human activities like burning coal have increased sulfur dioxide levels in the atmosphere and contributed to acid rain formation.
Rising human populations are largely responsible for the environmental degradation that ecological restoration seeks to repair.
the discipline of ecological restoration is likely to face its greatest challenges at a time when human capital and economic resources will be inadequate for the scale of the problem.
Restoration of damaged ecosystems is receiving increasing attention worldwide as awareness increases that humanity must sustain ecosystem structure, functioning, and diversity for its own wellbeing.
Restoration rebuilds an ecosystem little different than the pristine ecosystem that was degraded. It is done to the physical environment and to plants in restoration.
Definition of ecosystem restoration: ‘the process of assisting the recovery of an ecosystem that has been degraded, damaged, or destroyed’.
, there are many approaches to restoration, and the choice of approach should arguably be based on –

KEY ACTIVITIES FOR ECOSYTEM RESTORSTION
The document discusses various topics related to environmental science including energy flow in ecosystems, food chains and webs, ecological pyramids, succession, biogeochemical cycles, categories of ecosystems like grasslands and aquatic ecosystems, and biodiversity. It also covers natural resources like forests and food resources, and issues related to deforestation, mining in forests, dams and river valley projects, and afforestation programs.
The document discusses key concepts related to sustainability including:
- Sustainable development meets present needs without compromising future generations' ability to meet their own needs.
- Environmental indicators and ecological footprints can assess sustainability.
- The Millennium Ecosystem Assessment reported that humans have changed ecosystems more rapidly in the past 50 years than ever before, with mixed impacts on human well-being.
- Environmental impact assessments play an important role in sustainable development by evaluating potential impacts of projects.
Ecology is the science that studies the relationships between living organisms and their environment. It examines how populations of different species interact with one another and their habitat. Ecologists analyze the complex networks within ecosystems, which are composed of all the living and non-living components in a specific area. On the largest scale, the biosphere encompasses all life on Earth and the regions it inhabits, including the atmosphere, lithosphere, and hydrosphere.
This document provides an overview of current environmental issues facing the Earth. It discusses how human population growth and industrialization have negatively impacted the environment through increased consumption of non-renewable resources, pollution, and loss of biodiversity. As human societies developed from hunter-gatherers to agricultural to industrial, their demands on the environment expanded and dependence on fossil fuels rose, resulting in problems like pollution and depletion of resources. The core issues discussed are overconsumption, pollution, and biodiversity loss due to rising human populations. The document also introduces the concept of sustainability and the goal of creating a sustainable society that does not exceed the Earth's limits.

This document provides an overview of ecological systems and biomes. It begins by defining key ecological concepts like biotic and abiotic factors, and different levels of ecological organization from individuals to the biosphere. It then explains how solar energy input and topography shape physical environments and drive global atmospheric and ocean circulation patterns. This in turn influences the distribution of terrestrial biomes, which are distinguished by characteristic vegetation and are broadly determined by temperature and precipitation patterns. While climate is a primary factor, other influences like soils and fire also impact vegetation types.
The document summarizes key concepts about ecosystems, including trophic relationships and energy flow. It discusses primary producers, consumers, food chains, food webs, primary productivity, trophic efficiency, and nutrient cycles. It then covers the impacts of human activity such as habitat destruction, pollution, overpopulation, greenhouse effect, and overfishing. The document concludes by addressing the biodiversity crisis, major threats to biodiversity, endangered species conservation, and the goals of restoration ecology.
Diversity & Evolution - Organisms and their environmentthejohnnth
Organisms and their environments provide key terms in ecology such as habitat, ecological niche, predator, prey, population, community, and ecosystem. Energy flows through ecosystems in a non-cyclic manner from the sun to producers to consumers in food chains and food webs, while chemical elements cycle through the ecosystem. Pollution disrupts ecosystems and affects water quality by reducing dissolved oxygen levels, with impacts including eutrophication and harm to aquatic life. Conservation aims to maintain biodiversity and use natural resources sustainably.
ABSTRACT- Fresh water resources are not unlimited. The high rate of increase of human population of Nepal and the
rapid rate of industrialization have created problems of disposal of waste water products. The domestic wastes, excretory
materials of both human and animals and industrial effluents are discharged into the nearly lakes, rivers, reservoirs and
tanks and even in the catchment area of the above water bodies. The undesirable substances are regularly mixed into the
water of pond through surface run-off that degrades the water quality. Since last several years, there have been added an
array of agricultural pesticides and insecticides, which are further seriously aggravating the problem of pollution both for
public health and aquaculture. The detailed information of water quality and status of affected living organisms of water
bodies are necessary for the implementation of any management plan. The present investigation encompasses on plankton
identifying the ecological quality of Chhapakaiya pond Birgunj, Nepal. Seasonal sampling from all the sampling sites (site
A, B, C, D) in winter, summer and rainy season for period of 12 months (November 2014 – October 2015) at 9:00-11: 00
AM. A total of 27 taxa from different classes of zooplankton were reported. The zooplanktons were reported to be
maximum (774.4 unit/L) during summer and minimum (539.2 unit/L) during the rainy season in Chhapakaiya pond.

This document provides notes on ecosystems compiled by Dr. G Subbarao for environmental science students. It defines key ecosystem concepts like producers, consumers, decomposers, food chains, and food webs. It also explains ecological pyramids and how they illustrate the transfer of energy and biomass between trophic levels. Examples are given of various natural ecosystems like forests, grasslands, ponds, and oceans. Energy flow through ecosystems is described, with the sun as the main source of energy and photosynthesis enabling its transfer and transformation through food webs.
The document summarizes the major components of ecosystems, including abiotic and biotic factors. It discusses two major abiotic components - climatic factors like temperature, precipitation, and wind, and edaphic factors concerning soil properties. It also describes the major biotic components - producers, consumers, and decomposers. Producers like plants capture energy through photosynthesis while consumers feed on producers or each other. Decomposers break down dead organic matter and release nutrients.
Environmental, ecosystem and biodiversityusharanicivil
The document discusses key concepts in environmental science and ecology, including:
- The environment consists of biotic (living) and abiotic (non-living) factors. Main types of ecosystems are described like ponds, lakes, deserts and forests.
- Ecosystems have a flow of energy and cycling of materials between producers, consumers and decomposers. Succession over time leads to a climax community.
- Environmental studies are important for problem solving, maintaining ecological balance and sustainable development. Hazards can be physical, chemical or biological in nature.
An ecosystem is a functional unit consisting of living organisms interacting with each other and their non-living environment. Key components include producers, consumers, and decomposers interacting within a web of food chains and nutrient cycles. Energy enters through producers via photosynthesis and is transferred between trophic levels, with only 10% typically being transferred between adjacent levels as depicted in ecological pyramids. Ecosystems also cycle nutrients and undergo successional changes over time as conditions change.
Chemical communications among plant and animal components are fundamental elements for the functioning and the connectivity of ecosystems. In particular, wound-activated infochemicals trigger specific reactions of invertebrates according to evolutionary constraints, permitting them to identify prey cues, escape predators and optimize their behaviors according to specific life strategies.
This document discusses key terms related to how organisms interact with their environment, including habitat, niche, adaptation, biotic and abiotic factors. It describes various environmental influences on organisms like temperature, light, minerals, and water availability. Interactions between species such as competition, predation, parasitism, and mutualism are covered. Adaptations that help organisms survive things like stress or limited resources are discussed. Specific New Zealand organisms are used as examples.
This document summarizes the key biogeochemical cycles: the carbon, water, nitrogen, oxygen, phosphorus, and sulfur cycles. It provides brief descriptions of each cycle, explaining how the chemical element or compound moves through the biosphere, hydrosphere, and lithosphere. The carbon cycle involves the movement of carbon between organisms through photosynthesis, respiration, and combustion. The water and nitrogen cycles similarly describe the circulation of water and nitrogen between living things and the environment.
This document contains definitions of 69 ecology-related terms, including:
- Habitat: The place where organisms live
- Community: A collection of populations that interact with each other in a given area
- Ecosystem: All the biotic and abiotic factors in an area
- Biome: A group of ecosystems in the same region having similar types of vegetation governed by similar climatic conditions
- Ecology: The study of organisms and their interactions between them and their environment
1) Ecology is the scientific study of interactions among organisms and between organisms and their environment. The biosphere encompasses all life on Earth, including land, water, and air up to 8 km above and 11 km below the surface.
2) Ecology studies different levels of organization, from species to populations to communities to ecosystems and biomes. Energy flows through ecosystems from producers like plants to consumers at different trophic levels in food chains and webs.
3) Key biogeochemical cycles include the water, carbon, nitrogen, and phosphorus cycles which are essential to life and maintain conditions on Earth. Climate and latitude also influence global patterns of biomes and ecosystems.

Solution
Ecology :-The prefix \'eco\' has become synonymous with environmentally-friendly living. This
green fad, however, has more to do with conservation biology than with ecology, where the
prefix is borrowed from.All organisms, no matter their size, their species, or where they live,
need to interact with other organisms in their \'neighborhood\' and with their environment in
order to survive.Ecologyis the scientific study of the interactions between organisms and their
environment. The term comes from the Greek \'study of house\', or the study of the place we live
in.The scope of ecology is huge, and it encompasses all organisms living on Earth andtheir
physical and chemical surroundings. For this reason, the field is usually divided into different
levels of study including: organismal ecology, population ecology, community ecology and
ecosystem ecology.
Biogeography:-Biogeography is broken into two subcategories:*.Phytogeography, the study of
how plants are distributed on the earth*.
Zoogeography, the study of how animals are distributed on the earth (including
bacteria)Biogeography is very important in understanding how animals and plants have changed
the landscape over time. This field utilizes knowledge from the study of rocks or geology, the
study of ecosystems or ecology, and the study of the physical planet or physical geography to
answer questions about how organisms react to changes in their environment.
Ecosystem:-An ecosystem includes all of the living things(plants, animals and organisms) in a
given area, interacting with each other, and also with their non-living environments (weather,
earth, sun, soil, climate, atmosphere).
Photosynthesis:-Photosynthesis is the process used by plants, algae and certain bacteria to
harness energy from sunlight into chemical energy.There are two types of photosynthetic
processes: oxygenic photosynthesis and anoxygenic photosynthesis. Oxygenic photosynthesis is
the most common and is seenin plants, algae and cyanobacteria.undefined During oxygenic
photosynthesis, light energy transfers electrons from water (H2O) to carbon dioxide (CO2),
which produces carbohydrates. In this transfer, the CO2 is \"reduced,\" or receives electrons, and
the water becomes \"oxidized,\" or loses electrons. Ultimately, oxygen is produced along with
carbohydrates.
Respiration:-It may be associated with:*.breathing, which is the process of inhaling and exhaling
gases from and into theexternal environment– a function of the lungs and other structures with
similar function (e.g.gills)*.cellular respiration, which is the process utilized by cells to obtain
energy from theoxidationoforganic compoundsaccompanied by the consumption ofoxygen(when

that humans have on
the biogeochemical
cycles.
Ecology is the scientific study of the interactions among organisms and their environment. There are several key levels of ecological organization, including the biosphere, ecosystems, communities, populations, and organisms. Energy flows through ecosystems via food chains and webs, entering as sunlight and being lost as heat at each trophic level. Matter cycles through ecosystems as well, as nutrients are recycled from organisms to the environment and back again via processes like decomposition.
This 3-credit course on fundamentals of ecology covers key topics including definitions of ecology, historical background, classifications of ecology based on nature of study and type of environment, levels of ecological organization, feeding interactions like energy flow and trophic levels, and ecological interactions between organisms such as competition, niche, predation, and symbiosis. The course is taught in the 4th semester of the BS in Environmental Science program at NFC Institute of Engineering & Technology in Multan, Pakistan.
This document provides an introduction to ecology, defining key terms like organism, population, community, ecosystem, biome, and ecological niche. It discusses how ecologists study relationships between biotic factors (living things like plants and animals) and abiotic factors (non-living things like sunlight, temperature, soil) within ecosystems. Removal or addition of a single factor can impact the entire ecosystem, with some species playing an outsized role like a "keystone."
This document provides an overview of basic ecological principles and concepts:
- It describes biotic and abiotic factors that influence ecosystems, and defines producers, consumers, decomposers, and their roles in food chains, food webs, and trophic levels.
- It explains energy and biomass pyramids, and ecological interactions like competition, predation, and symbiosis.
- Succession and laws of minimum factors and tolerance are outlined, which influence plant growth and organism habitation.

This document provides an overview of environmental science and engineering concepts including the environment, ecosystems, and biodiversity. It defines key terms like environment, natural environment, man-made environment, abiotic components, biotic components, and energy components. It also describes the structure and functions of the atmosphere. Critical ecosystem concepts are explained like biome, producers, consumers, decomposers, energy flow, nutrient cycles, ecological succession, food chains, food webs, trophic levels, and ecological pyramids. Different types of ecosystems are classified as terrestrial or aquatic ecosystems.
This document discusses ecosystems and their structure and functions. It defines an ecosystem as including all living organisms and non-living components found in a particular area, where life continues naturally without human intervention. An ecosystem structurally consists of a community of living organisms and their abiotic environment. Key components include producers, consumers, and decomposers. Energy flows through ecosystems via food chains and webs. Nutrients cycle through biogeochemical cycles like carbon and nitrogen. Ecosystems strive for homeostasis by resisting changes to their populations.
The document discusses several key concepts related to ecosystems and biogeography:
1) It describes several important biogeochemical cycles (carbon, oxygen, nitrogen, water) that move key elements through ecosystems and influence plant and animal distributions.
2) It explains how solar energy flows through ecosystems via photosynthesis, primary production, and food chains/pyramids, with producers, primary consumers, and decomposers playing important roles.
3) It discusses factors that influence the natural distributions of plants and animals, such as evolutionary history, migration/dispersal abilities, and reproductive success within local environmental conditions.
This document discusses ecosystems and their components. It defines key terms like ecosystem, ecological niche, food chain, food web, trophic levels, and ecological pyramids. It also briefly outlines different types of ecosystems like terrestrial, estuarine, ocean, and freshwater. Finally, it presents some sample multiple choice questions and answers about ecosystems, food chains, and biogeochemical cycles.

It provides the definition for each term, including absolute zero, solute, solvent, solution, dissociation, dispersion, ionization, solubility, saturated solution, unsaturated solution, supersaturated solution, concentration, morality, acid, base, neutralization, salt, pH, electrolyte, acid-base indicator, non-electrolyte, and alloy.
This document defines 23 terms related to phases of matter and their properties. It defines key concepts like absolute zero, the lowest theoretically possible temperature; boiling, the process of a liquid becoming a vapor; boiling point, the constant temperature at which a liquid boils; and the three main states of matter - solids, liquids, and gases. It also outlines physical properties like density, heat transfer terms, vapor pressure, and kinetic energy of particles.
The document is a review of meiosis which includes images and questions. Meiosis is the process of cell division that results in gametes or sex cells with half the normal number of chromosomes. It involves two rounds of division called meiosis I and meiosis II, which produces four daughter cells each with half the number of chromosomes of the original cell. The review covers the key stages and steps in meiosis including prophase I, metaphase I, anaphase I, telophase I and cytokinesis.
1) Meiosis is a type of cell division that produces gametes (sex cells) with half the number of chromosomes as the parent cell. It occurs in two stages, Meiosis I and Meiosis II, resulting in four daughter cells each with half the chromosome number.
2) During Meiosis I, homologous chromosomes pair and crossover can occur, separating the parental chromosomes. This reduces the chromosome number from diploid to haploid.
3) Meiosis II then separates the sister chromatids, resulting in four unique haploid daughter cells that can fuse during fertilization.
The document provides instructions for a meiosis phase review activity. It directs the user to identify the phases of meiosis on subsequent slides, say the picture number for each phase, and check their answer. The activity tests the user's learning of the order and process of the different phases of meiosis.
