There are actually quite a few different cycles that will produce oxygen. Photosynthesis in plants is just one of these cycles.
the water cycle
Trees provide oxygen for us but it also provides it for water as well. Water is made up of Hydrogen and Oxygen. If we keep on cutting down trees (logging) it will effect thewater-cycle.

Producers is the group of organism that is a source in the oxygen cycle.
Their is recycled air in the carbon dioxide and oxygen cycle and no recycled air in the carbon cycle.
The carbon dioxide-oxygen cycle is the cycle in which living things (such as plants and animals) take in "oxygen" and let out "carbon dioxide."
No oxygen is used in TCA cycle. Oxygen comes into play in the electron transport chain.
Oxygen cycle is the movement of oxygen through the three reservoirs: the atmosphere, the biosphere and the lithosphere.
The two processes that take place during the oxygen cycle would be cellular respiration and photosynthesis. The oxygen cycle is also known as the carbon cycle.
