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,after accounting for the energy lost during respiration $(R)$.Mathematically,$NPP = GPP - R$,where $GPP$ is Gross Primary Productivity.Since $NPP$ specifically refers to the energy stored by plants (producers) that is available for consumption by heterotrophs,it is a characteristic attribute of the producer level in an ecosystem.Therefore,the correct option is $A$.

At which of the following levels can Net Primary Productivity $(NPP)$ be obtained?
