The oxygen and carbon cycles are tightly linked by biological and chemical redox reactions: photosynthesis converts carbon dioxide and water into organic carbon while releasing oxygen, and respiration, decomposition and combustion reverse that process by consuming oxygen and returning carbon dioxide to the atmosphere. Oceans exchange CO2 and O2 with the atmosphere and host large biological sinks, and on geological timescales burial of organic carbon raises atmospheric O2 while weathering and oxidation consume it. In short, moves of carbon between reservoirs drive complementary moves of oxygen, so changes in one cycle affect the other.
