WebThe equations below describe them. Light bottle: In the light bottle, there is photosynthesis, or Gross Primary Production (GPP), and there is Respiration (R). The difference between these two processes, as we saw above, is Net Primary Production = NPP = (GPP - R) Dark bottle: In the dark bottle, there is no photosynthesis and only respiration. 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).
