Diagram showing the main organic C stocks and fluxes, and GHG fluxes, in a forest. C enters the trees through photosynthesis. Leaf litter and root loss transfer C to the soil C stock. Respiration by plants, fungi and soil bacteria release stored carbon, as does disturbance and leaching of organic carbon in the soil. Nitrous oxide is released by soil bacteria; methane is both released from and taken up by soil bacteria.
