Question

How can you say that forests are biosphere reserves? Give reasons.

Answer 1

Biosphere actually means a place where there is interaction between the three elements of earth land(lithosphere), water(hydrosphere), air(atmosphere).We can say that forests are biosphere reserves as it is a place having a large ecosystem and there is abundance of interaction between the elements in a forest. Animals, plants co exist with each other. It is a place where dependency of living organisms on each other can be seen.
