Oxygenic photosynthesis functions as a counterbalance to respiration it takes in the carbon dioxide produced by all breathing organisms and reintroduces oxygen. Oxygenic photosynthesis chlorophototrophy can further be divided into oxygenic photosynthesis and anoxygenic phototrophy. Habitats in which oxygenic photosynthesis is important is relatively limited in distribution and is therefore restricted to shallow coastal sediments or coral lagoon.
