This article provides a diagram of the oxygen cycle.
Oxygen Cycle is one of the major gaseous components of atmosphere. The oxygen cycle involves movements and storages in different forms and its oxidative reactions with various elements.
The world supply of O2 is shown in Fig. 5.20:
Oxygen enters this storage pool through release in photosynthesis-both in the oceans and on the lands. Balancing the input to the atmospheric storage pool is loss through organic respiration and mineral oxidation. The oceans serve as a major storage pool for dissolved gaseous oxygen some oxygen is continuously placed in storage in mineral carbonate form in ocean floor sediments.
