    How does the carbon dioxide enter the biosphere and how does the oxygen flow off?

      This is a pretty technical explanation, but worth the watch if you're interested.. Basically, gasses exchange on the surface of the water. Wind, rain, and other meteorological events can increase the exchange rate. Then aquatic organisms "pull" the carbon dioxide or oxygen into the hydrosphere further through respiration, photosynthesis, and other basic life functions. In reality, more carbon dioxide is absorbed than is released. This phenomenon is causing ocean acidification, one of the consequences of climate change.
