Types of coral reefs and its distribution
Coral reefs are underwater structures composed of calcium carbonate secreted by tiny animals called coral polyps. Coral polyps have stinging tentacles and live in symbiosis with algae. This mutualistic relationship provides nutrients and protection. Coral reefs occupy less than 1% of the ocean but support 25% of marine species. They act as barriers, provide habitat, sequester carbon, and have significant economic importance through tourism, fisheries, and medicine. The largest reefs are the Great Barrier Reef and Belize Barrier Reef.
Ecology and Ecosystem
This document provides an overview of ecology and ecosystems. It defines ecology as the study of the relationships between living organisms and their environment. The key components of ecosystems discussed include producers, consumers, decomposers, trophic levels, food chains, food webs, and biogeochemical cycles. Specific cycles explained in detail are the water, carbon, oxygen, and nitrogen cycles which describe how these essential elements move between living and nonliving parts of the environment.
Concept and characteristics of biodiversity
Biodiversity refers to the variety of life on Earth across genes, species, and ecosystems. It is estimated that 1.7 million species have been described, with insects making up the largest group. Biodiversity provides intrinsic value as well as utilitarian value through services like food, medicine, and ecosystem functions. However, biodiversity is declining rapidly due to factors like habitat loss, pollution, and climate change. Maintaining biodiversity is important for ecological stability and human well-being.
5. Ecology and evolution
The document discusses the IB Diploma Programme and the IB Learner Profile. The IB Learner Profile describes the attributes that IB aims to foster in students. It includes being inquirers, knowledgeable, thinkers, communicators, principled, open-minded, caring, risk-takers, balanced, and reflective. The profile emphasizes developing curiosity and strong thinking skills in an international and caring context.
Introduction To Ecology
This document introduces the key concepts of ecology, including:
1) Ecology is the study of how organisms interact with their environment and each other.
2) Organisms are organized into levels ranging from cells to the biosphere.
3) The environment consists of biotic and abiotic factors that surround organisms.
4) All organisms are interdependent and interact through competition, predation, and nutrient recycling.
Ecological Interactions - Mutualism, Commensalism & Neutralism
Ecological interactions are the effects an organism have on another in an ecosystem. This slide describes Mutualism, Commensalism and Neutralism with examples.
Biodiversity ist lecture
This document discusses biodiversity, including its definition, importance, levels, threats, and patterns. It defines biodiversity as the variety of organisms within an ecosystem and notes it involves more than just species counts. It outlines how biodiversity benefits the global economy through agriculture, recreation, and trade. It then describes the three main levels of biodiversity - genetic, species, and ecosystem diversity. The document also discusses threats like habitat destruction, overexploitation, pollution, and climate change. It notes patterns involving vulnerable species groups like rare, long-lived, and keystone species. Finally, it contrasts conservation with preservation approaches to biodiversity management.
Species diversity (PLANT ECOLOGY)
Species diversity is defined as the number of different species present in an ecosystem and their relative abundances. There are two components of species diversity: species richness, which is the number of different species present, and species evenness, which is how similar the abundances of each species are. Tropical rainforests and coral reefs have very high species diversity due to favorable environmental conditions that allow for many specialized species and resilience to disturbances. However, human activities like habitat loss, overexploitation, invasive species, and extinctions are major threats and causing accelerated extinction rates. Conservation efforts focus on both in-situ and ex-situ methods to protect biodiversity.

Ppt on biodiversity
This document discusses biodiversity, which refers to the variety of plant and animal life on Earth. It notes that biodiversity is important for providing humans with shelter, food, water, health, land, medicine and air. Biodiversity exists at the genetic, species, and ecosystem levels. The document outlines factors threatening biodiversity like habitat loss and pollution, and the consequences of biodiversity loss such as fewer ecosystem services. Protecting biodiversity is important for food security, natural resources, and the economy. The document concludes by stating that global warming is negatively impacting biodiversity.
Importance of biodiversity to humanKinds
Biodiversity is essential for human well-being and survival. It provides vital goods and services like food, medicine, clean air and water. Each species, no matter how small, plays an important role in ecosystem productivity and sustainability. At least 40% of the global economy and 80% of needs of poor people are derived from biological resources. Biodiversity also has immense aesthetic, cultural and spiritual value for humans. While we have benefited from biodiversity in many known ways, most of its benefits are still unknown as important species and ecosystem functions have yet to be discovered. Loss of biodiversity therefore poses a major threat to humanity's future welfare and progress.
Principles of ecology
Ecology is the scientific study of interactions between organisms and their environment. The components of ecology include abiotic (non-living) factors like temperature and biotic (living) factors like other organisms. A niche describes an organism's role and interactions within its ecosystem, including how it meets its needs. Relationships between organisms in an ecosystem can be symbiotic like mutualism, or involve one organism benefiting more than the other like parasitism or commensalism. Natural selection leads to evolution as organisms with traits better suited to their environment are more likely to survive and pass on those traits, changing the gene frequency in a population over time. Speciation occurs when reproductive isolation splits one species into two distinct species.
Biodiversity and stability
This document discusses biodiversity and population ecology. It defines biodiversity as the variety of life forms in an ecosystem. Organisms have economic, ecological, and aesthetic value. They are important for ecosystem balance and provide goods like food, medicine, clothing, and energy. The document also discusses population size, birth and death rates, carrying capacity, and factors that influence populations like resources, natural disasters, competition, predation, and diseases. It notes that the Philippines has high biodiversity but it is threatened by habitat loss and overexploitation of resources.
A brief presentation on Terrestrial Ecosystem
The document provides information about different types of terrestrial ecosystems. It defines terrestrial ecosystems as ecosystems that occur on land, as opposed to aquatic ecosystems. It notes that terrestrial ecosystems make up 28% of the world's area but contain much more variability in flora and fauna compared to aquatic ecosystems. The document then describes the major classifications of terrestrial ecosystems as biogeographic realms and biomes. It provides details on the six biogeographic realms and seven major biomes that characterize different terrestrial regions based on their climate and plant/animal life.
Extinction
Local, ecological, and biological extinction are defined. Population genetics and limited geographic range increase extinction risk, while habitat degradation from agriculture, urbanization, and other human activities is currently the main cause of species extinction. Introduction of new competing species and climate change further threaten biodiversity by causing extinctions, while conservation efforts aim to protect endangered species and ecosystems.
Measuring Biodiversity
This slideshow was created for the VCE Environmental Science Online Course, Unit 3: Biodiversity. It explains different methods of assessing biodiversity and discusses several indices for measurement.
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
Echologicalconcepts and principles
This document provides an overview of ecological concepts and principles of ecosystems. It defines ecology and describes the basic units of ecological systems from protoplasm to the biosphere. Key concepts discussed include populations, communities, ecosystems, food webs, and the abiotic and biotic components of ecosystems. Four principles of ecosystems are outlined: everything is related, everything must go somewhere, nature knows best, and there is no free lunch. Factors affecting ecosystems and environmental health are also summarized.

Species diversity
1. Species diversity refers to the number and variety of species in a given region. It takes into account both the number of species and how evenly abundant they are.
2. There are three main types of species: endemic, exotic, and cosmopolitan. Endemic species are restricted to a particular area while exotic species have been transported by humans.
3. Factors that affect species diversity include speciation, extinction, migration, habitat destruction, and the introduction of invasive species. Speciation occurs through geographic isolation or reductions in gene flow. Extinction can be caused by overharvesting, pollution, and habitat loss.
Invasive Species.pptx
Invasive species are non-native organisms that cause harm to the environment, economy, or human health. They spread rapidly and outcompete native species due to a lack of natural predators. Common modes of transmission include shipping, boats, wood/soil transport, release of pets/ornamentals, and climate change. Invasive species directly prey on, outcompete for resources, or introduce diseases to native wildlife. They can also indirectly impact ecosystems by altering habitats and food webs. Several invasive plant and animal species from around the world are provided as examples, including their origin, spread, and impacts.
4.3 Conservation of Biodiversity
This document discusses arguments for preserving biodiversity. It notes that biodiversity provides direct values like food sources and natural products, as well as many indirect values. These indirect values include ecosystem productivity, scientific/educational value, biological control, genetic resources, environmental monitoring, recreation, human health, human rights, intrinsic value, and facilitating future conservation efforts. The document also discusses international conventions and protected area design. It evaluates approaches to conservation at the species, area, and ecosystem levels and considers debates around reserve size and design.
Extinction of biodiversity
The document discusses extinction and biodiversity loss. It defines extinction as occurring when the last member of a species dies. The passenger pigeon is provided as an example, with the last one dying alone in a zoo in 1914 after the species was already functionally extinct in the wild. Major causes of extinction discussed include habitat degradation and destruction from human activities like pollution, climate change, and overpopulation. Statistics are given on current extinction rates from human impacts being 1500 times the natural rate, with many species projected to be lost in the coming centuries if trends continue. The major impacts of biodiversity loss on human concerns like medicine, agriculture, ecosystem services, and moral obligations are also briefly touched on.
Community Ecology
The document summarizes key concepts in community ecology:
1. Community structure is described by physical appearance, species diversity, and niche structure.
2. Species diversity is influenced by factors like latitude and pollution.
3. The number of species on an island is determined by immigration and extinction rates, island size, and distance from mainland.
4. Species play roles like native, non-native, indicator, keystone, and foundation species that impact community ecology.
The components of an ecosystem
The structural components of an ecosystem consist of nonliving arena and the living organisms.
They are terms as Abiotic compounds and Biotic compounds.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
Wound healing PPT
This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
