Vedclass · Answer

(B) Gross Primary Productivity $(GPP)$ of an ecosystem is the rate of production of organic matter during photosynthesis by producers.Producers,such as plants and algae,capture solar energy and convert it into chemical energy in the form of biomass.Therefore,$GPP$ represents the total amount of biomass or organic matter synthesized by the producers in an ecosystem per unit area over a specific time period.Option $B$ is the correct definition.

Column-$I$	Column-$II$
$(a)$ $\text{NPP}$ of ocean	$(i)$ $115$ billion tons
$(b)$ Annual $\text{NPP}$ of the whole biosphere	$(ii)$ $170$ billion tons
$(c)$ $\text{NPP}$ of terrestrial ecosystem	$(iii)$ $55$ billion tons
$(d)$ Secondary productivity	$(iv)$ Heterotrophs

Gross Primary Productivity $(GPP)$ is defined as:
