<P> The carbon exchanges between reservoirs occur as the result of various chemical , physical , geological , and biological processes . The ocean contains the largest active pool of carbon near the surface of the Earth . The natural flows of carbon between the atmosphere , ocean , terrestrial ecosystems , and sediments is fairly balanced , so that carbon levels would be roughly stable without human influence . </P>
