How is npp derived from gpp
WebNet Primary Production (NPP) = GPP – R A The amount of organic carbon produced by plants that is not consumed by their own respiration. It is the increase in the plant biomass in the absence of herbivores. For an entire ecosystem:Some of the NPP of the plants is consumed (and respired) by herbivores and decomposers and oxidized back to CO 2(R H).
