oxygen cycle is the cycle thathelps move oxygen through the main three regions of the earth , the atmosphere, the biosphere and the lithosphere. The Atmosphere is of course the region of gases that lies above the earth's surface and it is one of the largest reservoirs of free oxgen on earth. The Biosphere is the sum of all the Earth's ecosystems. This also has some free oxygen produced from photosynthesis and other life processes. The largest reservoir of oxygen is the lithosphere.Most of this oxygen is not on its own or free moving but part of chemical compounds such as silicates and oxides.
