Vedclass · Answer

(B) Net Primary Productivity $(NPP)$ is the rate of storage of organic matter in plant tissues in excess of the respiratory utilization by plants during the measurement period.Mathematically,it is expressed as: $NPP = GPP - R$,where $GPP$ is Gross Primary Productivity and $R$ is the energy lost through respiration by the producers.Therefore,it represents the biomass available for consumption by heterotrophs (herbivores and decomposers).

List-$I$ (Process)	List-$II$ (Definition)
$A$. Productivity	$I$. Gross primary productivity minus respiration losses
$B$. Net primary productivity	$II$. Rate of formation of new organic matter by consumers
$C$. Gross primary productivity	$III$. Rate of biomass production
$D$. Secondary productivity	$IV$. Rate of production of organic matter during photosynthesis

Net Primary Productivity $(NPP)$ is defined as:
