List two ways in which the biosphere would be impacted in the absence of the geosphere. use complete sentences.

The biosphere is simply "life on Earth"—the sum total, that is, of all living things on Earth. Yet the whole is more than the sum of the parts: not only is the biosphere an integrated system whose many components fit together in complex ways, but it also works, in turn, in concert with the other major earth systems.  These and many other interactions make it easy to see why scientists speak of Earth as a system—and why some go even further and call it a living thing.
