Vedclass · Answer

(A) 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.It is calculated by subtracting the respiratory losses $(R)$ from the Gross Primary Productivity $(GPP)$.Mathematically,$NPP = GPP - R$.Since $GPP$ represents the total weight of organic matter produced by green plants through photosynthesis,the $NPP$ is the total weight of green plants (biomass) minus the respiratory losses.
