  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.

Variations within an ecosystem can cause genetic drifts. Variations will cause those organisms to survive which are better adapted to survive to the changes which occur in an ecosystem. 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.

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
