Vedclass · Answer

(B) Secondary production is defined as the rate of formation of new organic matter by consumers.In an ecosystem,energy flows from producers to consumers. According to the $10 \%$ law of energy transfer,only $10 \%$ of the energy available at one trophic level is transferred to the next trophic level.In the given pyramid:$1$. Solar radiation $(IV)$ = $100,000 \; kcal / m^{2} / yr$.$2$. Primary producers $(III)$ utilize $1 \%$ of solar radiation = $1,000 \; kcal / m^{2} / yr$.$3$. Primary consumers $(II)$ receive $10 \%$ of the energy from primary producers = $100 \; kcal / m^{2} / yr$.Since primary consumers are the first level of consumers,the energy stored by them represents secondary production.Therefore,the rate of secondary production is $100 \; kcal / m^{2} / yr$.
