2. The Environment To the ecologist, the  environment  of an organism includes both physical aspects and other organisms. These two components of the environment are called abiotic and biotic components, respectively. •  Abiotic components , or abiotic factors, are the non-living physical aspects of the environment. Examples include sunlight, soil, temperature, wind, water, and air. •  Biotic components , or biotic factors, are the living organisms in the environment. They include organisms of the same and different species. 2 7/12/2021 Add a footer

3. Ecology is the scientific study of the interactions of living things with each other and their relationships with the environment. The word comes from the Greek oikos, meaning “household,” “home,” or “place to live.” Thus, ecology deals with the organism and its environment. The concept of environment includes both other organisms and physical surroundings. It involves relationships between individuals within a population and between individuals of different populations. Ecology is guided by a number of basic principles. One principle is that each living organism has a continual relationship with every other element in its environment. In this context, the environment includes both living and nonliving components. 3 7/12/2021 Add a footer ECOLOGY

4. INTERRELATEDNESS OF ENVIRONMENT AND THE ECOLOGY

5. 5 7/12/2021 Add a footer Environment is everything that surrounds us, whereas, ecology is how all those work. It refers to the study of interaction of the organisms with their environment . Ecology seeks to understand life process, adaptation and biodiversity. Environment, on the other hand, aims to identify the internal and external factors that affect population. Ecology and environment  are two aspects of nature and its study that have taken center stage today. This is both because of degradation of the environment through pollution as well as changes in ecology caused by natural forces. As both ecological and environmental studies are about inter-related concepts

6. Organisms An  organism  is a life form consisting of one or more cells. All organisms have properties of life, including the ability to grow and reproduce. These properties of life require energy and materials from the environment. Therefore, an organism is not a closed system. Individual organisms depend on and are influenced by the environment. 6 7/12/2021 Add a footer

7. 7 7/12/2021 Add a footer  P opulation  consists of organisms of the same species that live in the same area and interact with one another. Important ecological issues at the population level include: • Rapid growth of the human population, which has led to overpopulation and environmental damage; • Rapid decline in populations of many nonhuman species, which has led to the extinction of numerous species.   Community  consists of populations of different species that live in the same area and interact with one another. 

8. 8 7/12/2021 Add a footer Ecosystem A community can also be defined as the biotic component of an ecosystem. An  ecosystem  is a natural unit consisting of all the living organisms in an area functioning together with all the nonliving physical factors of the environment. The concept of an ecosystem can apply to units of different sizes. For example, a large body of fresh water could be considered an ecosystem, and so could a small piece of dead wood. Both contain a community of species that interact with one another and with the abiotic components of their environment.

9. 9 7/12/2021 Add a footer Niche One of the most important ideas associated with ecosystems is the niche concept. A  niche  refers to the role of a species in its ecosystem. It includes all the ways species’ members interact with the abiotic and biotic components of the ecosystem. Two important aspects of a species’ niche include the food it eats and how it obtains the food. Figure 3 shows pictures of birds that occupy different niches.

11. 11 7/12/2021 Add a footer Habitat Another aspect of a species’ niche is its habitat. A species’  habitat  is the physical environment to which it has become adapted and in which it can survive. A habitat is generally described in terms of abiotic factors, such as the average amount of sunlight received each day, the range of annual temperatures, and average yearly rainfall. These and other factors in a habitat determine many of the traits of the organisms that can survive there . Human destruction of habitats is the major factor causing other species to decrease and become endangered or go extinct.

15. 15 7/12/2021 Add a footer ENVIRONMENTAL ETHICS

16. ENVIRONMENTAL ETHICS is a branch of applied philosophy that studies the conceptual foundations of environmental values as well as more concrete issues surrounding societal attitudes, actions, and policies to protect and sustain biodiversity and ecological systems.   is the philosophical discipline that considers the moral and ethical relationship of human beings to the environment. 16 7/12/2021 Add a footer

17. There are many different environmental ethics one could hold, running the gamut from human-centered (or "anthropocentric") views to more nature-centered (or "non-anthropocentric") perspectives. Anthropocentric Regarding humankind as the central or most important element of existence, especially opposed to God or animals. Non- anthropocentrists - argue for the promotion of nature's intrinsic, rather than instrumental or use value to humans.   17 7/12/2021 Add a footer

18. Importance of Environmental Ethics Makes us aware of the indiscriminate and destructive human activities. Inculcate moral values towards nature and learn to respect various life forms through environment ethics. Concerned with the issues of responsible personal conduct with respect to natural landscape, resources, species, and nonhuman organisms. Conduct with respect to persons is, of course, the direct concern of modern philosophy. 18 7/12/2021 Add a footer
