    The Carbon and Oxygen Cycles

The Carbon and Oxygen Cycles

Carbon and oxygen are two elements that are essential to life. They are naturally present in the atmosphere in the form of carbon dioxide and gaseous oxygen. Due to their constant circulation between the soil, air, and water--through processes such as photosynthesis and combustion--living matter is constantly renewed. However, human activities can disturb the balance of these cycles.
