As part of the biosphere, all living organisms on the earth interact and changes the other spheres in one way or the other.

We breathe out carbon dioxide and take in oxygen into our bodies. Hydrosphere: we also need water for various life processes. Water is essential for all living organisms. It makes up the bulk of the body parts of human beings. The different forms of water in the environment also have important consequences on the climate patterns.
