The Short Term Carbon Cycle: changes from year to year and decade to decade
The dominant chemical reactions are:
Photosynthesis: CO2 + H2O ----sunlight----> CH2O + O2
(carbon dioxide, water and sunlight yield carbohydrate and oxygen)Respiration: CH2O + O2 -> CO2 + H2O
(carbohydrate and oxygen yield carbon dioxide and water and energy)Fermentation: 2CH2O -> CO2 + CH4
(carbohydrate decomposes to carbon dioxide and methane)Combustion: (Organic Carbon, C, H, O) + O2 -> CO2 + H20 + energy
(hydrocarbon and oxygen yield carbon dioxide and water and energy) [anthropogenic]
