Carbon and Water Cycles

Water and carbon, along with other biogeochemical processes, occur in cycles. Water cycles through evaporation, condensation, precipitation, and runoff where it accumulates before the water evaporates and the cycle begins. The carbon cycle begins with carbon reservoirs. First, plants take in carbon dioxide then release carbon when they are either eaten, start decomposing, or during respiration.  Second, the ocean takes in a lot of carbon dioxide because of organisms like phytoplankton and others who create calcium carbonate shells that settle in the ocean and eventually the carbon is put into the newly created limestone. Limestone, when eroded, releases carbon dioxide into the air along with creating carbonic acid.
