Variations Within Ecosystems
Ecosystem diversity can be described as a term which is used o describe the changes within an ecosystem and the impact these changes have on the environment and humans.

And the organisms which are not better suited become extinct over a period of time. Hence, this will lead to a wide rise in biodiversity.
