40 The total rate at which producers synthesise organic material is called gross primary productivity (GPP). The rate at which producers store organic material as new tissue is called net primary productivity (NPP). What shows the relationship between GPP and NPP? A NPP = GPP × respiration B NPP = GPP ÷ respiration C NPP = GPP + respiration D NPP = GPP – respiration
