How is oxygen recycled in an aquatic environment?
Oxygen is recycled in an aquatic environment in much the same way as it is on land. Phytoplankton, diatoms, seaweeds, and other underwater autotrophs use the sun's light to perform photosynthesis and release some of the oxygen produced in this process as a waste product. That oxygen is breathed in by aquatic animals and these animals exhale carbon dioxide because of respiration, which is necessary in the photosynthesis process by the autotrophs.
