If I recall correctly, the levels of oxygen in the air are kept very close to 21% by the biosphere. If the level rises, even a little bit, the air becomes more flammable, forest fires increase, CO2 is released, and the level returns to close 21%. If the level decreases something equivalent happens, that now I can't remember.
