Oxygen cycle From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search The oxygen cycle. The Oxygen cycle is the biogeochemical cycle that describes the movement of oxygen within its three main reservoirs: the atmosphere (air)‚ the total content of biological matter within the biosphere (the global sum of all ecosystems)‚ and the lithosphere (Earth ’s crust). Failures in the oxygen cycle within the hydrosphere (the combined mass of water found on‚ under‚ and over the surface of a planet)
