What effect do you have on the Earth system? As a part of the biosphere, think of some ways that you change the atmosphere, hydrosphere, or geosphere.

Explanation:

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

Here are some of the ways we change the other spheres:

Atmosphere: through the biological process of respiration, gaseous exchange occurs between organisms and the surrounding pool of gases around. 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. Geosphere: is the solid part of the earth. It provides habitation for some organisms. Most of the rocks used from construction come from the geosphere of the earth.
