The Oxygen Cycle

Oxygen is essential for life......  (e.g. respiration, stratospheric ozone)
     ...... but what supplies the oxygen consumed by living beings?
  • oxygen is created by photosynthesis and net emission due to burial of atmospheric carbon (CO2)
  • oxygen is consumed by both living beings and the net uptake of oxygen due to weathering of fossilized carbon
