Question

Species of plants and animals found exclusively in a particular area are termed as _______.

Answer 1

Hint: An ecosystem composed of biotic and abiotic components. This includes the study of two basic categories; aquatic and terrestrial. The forest, desert, and grassland are terrestrial ecosystems and the pond, lakes, and other water bodies are aquatic ecosystems.

Complete Answer:
- An ecosystem is the interaction between the biotic and the abiotic components that forms a structure. Through the identification of the different plants and animals species of an ecosystem gives its species composition. The productivity, decomposition, energy flow, and the nutrient cycling is considered as the unit that functions together to understand the component of the ecosystem.
- To understand this better, let’s take the example of an aquatic ecosystem, in a pond the abiotic component is the water and the inorganic and organic compounds dissolved in it and the soil deposit.
- The autotrophic components are the phytoplankton, the floating, and some of the algae. The consumers are the zooplanktons, decomposers are the bacteria, fungi, and flagellates, therefore this system has all the functions of an ecosystem.
- An important characteristic of all the communities is that their structure and composition changes constantly due to the change in environmental conditions. This change is sequential and orderly, parallel with the changes in the environment. This change leads to a formation of community that is almost equilibrium with the environment and is termed as climax community.
- Now, endemic species are the species that are found in a particular area and nowhere else in the world. Endemism is the ecological state of species that defines the particular geographic location like island, country, nation, and defined zone or type of habitat.

Note: The indigenous organisms of a place are not endemic if that species are found somewhere else. The area where different types of flora and fauna are found is considered as biodiversity.
