Vedclass · Answer

(B) In an ecosystem,primary productivity is defined as the rate at which biomass or organic matter is produced per unit area by producers (plants) during photosynthesis.Secondary productivity is defined as the rate of formation of new organic matter by consumers (heterotrophs).Since secondary consumers are heterotrophs that consume organic matter to build their own biomass,the energy available at this level is a result of secondary productivity.Therefore,the correct option is $B$.
