Vedclass · Answer

(A) The correct option is $A$. Net primary productivity $(NPP)$ is the biomass available for consumers (herbivores and decomposers) for consumption. Gross primary productivity $(GPP)$ of an ecosystem is the rate of production of organic matter during photosynthesis. During respiration $(R)$,organic compounds are oxidized to release energy,producing carbon dioxide and water. Therefore,when the energy lost through respiration $(R)$ is subtracted from the total gross primary productivity $(GPP)$,we obtain the net primary productivity $(NPP)$. Mathematically,this is expressed as: $NPP = GPP - R$.

Net primary productivity $(NPP)$ in an ecosystem is:
