THE FINAL LEVEL OF ORGANIZATION
A biosphere is the part of Earth that contains all the ecosystems or the part of Earth in which life exists. A biosphere can be air, water, land or even the atmosphere. Our biosphere extends about kilometers from Earths surface and up to 11 kilometers below Earths surface. Since Earth is the only planet that is able to support life,all biospheres are located on Earth. All life is interdependent on each other and is connected within the biosphere. |
