Vedclass · Answer

(A) According to the ecological efficiency,green plants (producers) trap only about $1 \; \%$ of the solar energy incident on them.Given solar energy = $2000 \; J$.Energy trapped by producers $(A)$ = $1 \; \%$ of $2000 \; J = (1/100) 	imes 2000 = 20 \; J$.According to Lindeman's $10 \; \%$ law,only $10 \; \%$ of the energy is transferred to the next trophic level.Energy transferred to herbivores $(B)$ = $10 \; \%$ of $A = 10 \; \%$ of $20 \; J = 2 \; J$.Energy transferred to carnivores $(C)$ = $10 \; \%$ of $B = 10 \; \%$ of $2 \; J = 0.2 \; J$.Thus,$A = 20 \; J, B = 2 \; J, C = 0.2 \; J$.

Suppose $2000 \; J$ of solar energy is incident on green vegetation. On the basis of the $10 \; \%$ law of Lindeman,identify $A, B$ and $C$ as shown in the figure.
