Terrestrial
gross photosynthesis annually fixes about 120×10^15gC
(440×10^15gCO2) from the atmosphere’s 730×10^15gC (primary ref).
The global distribution of this flux parallels the distribution of
transpiration, indicating the closely coupled controls of stomata on
CO2 and water vapour diffusion. See BNID 109839 |
