Oxygen cycle. From Wikipedia, the free encyclopedia. Jump to: navigation, search. The oxygen cycle is the biogeochemical cycle that describes the movement of oxygen within and between its. three main reservoirs: the atmosphere (air), the biosphere (living things), and the lithosphere (Earth's crust). The main driving factor of the oxygen cycle is photosynthesis, which is responsible for the modern Earth's. atmosphere and life. [edit] Reservoirs and Fluxes.
The global carbon cycle is now usually divided into the following major reservoirs of carbon interconnected by pathways of exchange: 1  The atmosphere. 2  The terrestrial biosphere. 3  The oceans, including dissolved inorganic carbon and living and non-living marine biota.
