Vedclass · Answer

(D) Net Primary Productivity $(NPP)$ is defined as the amount of biomass or organic matter produced by producers per unit area per unit time,which is available for consumption by heterotrophs (herbivores and decomposers).Mathematically,it is calculated by subtracting the energy used by plants for respiration $(R)$ from the Gross Primary Productivity $(GPP)$.The formula is: $NPP = GPP - R$.Therefore,both statements $A$ and $B$ correctly describe $NPP$.
