Question

3. What is Biosphere? How is it connected with the other realms?​

Answer 1

All life respirates (i.e. extracts elements from the atmosphere) & uses water (the hydrosphere) to carry nutrients to the various parts of their bodies. Even without a biosphere, the other three realms will exchange constituents as the elements constantly undergo phase changes from solid to liquid to gas.
