Net Primary Productivity

Vedclass · Answer

(A) $1$. Gross Primary Productivity $(GPP)$ is the rate of production of organic matter during photosynthesis by producers.$2$. Net Primary Productivity $(NPP)$ is the $GPP$ minus respiration losses $(R)$,i.e.,$NPP = GPP - R$.$3$. $NPP$ represents the biomass available to heterotrophs (herbivores and decomposers) for consumption.$4$. Therefore,the biomass available to herbivores and decomposers is the Net Primary Productivity $(NPP)$.

The biomass available to herbivores and decomposers is known as:
