The Biosphere
The biosphere is made up of all living things on Earth and the parts of the geosphere, hydrosphere, and atmosphere they depend on to survive. Living things do not just depend on the other three systems, they actively change them too, for example by adding oxygen to the atmosphere or breaking down rock into soil.
