Vedclass · Answer

(B) According to the $10 \%$ law of energy transfer in an ecosystem,only $10 \%$ of the energy available at one trophic level is transferred to the next higher trophic level.Given: Energy at the producer level (Grass) = $4000 \ J$.$1$. Energy available to the primary consumer (Grasshopper) = $10 \%$ of $4000 \ J = 400 \ J$.$2$. Energy available to the secondary consumer (Frog) = $10 \%$ of $400 \ J = 40 \ J$.$3$. Energy available to the tertiary consumer (Snake) = $10 \%$ of $40 \ J = 4 \ J$.Therefore,the energy available to the frog is $40 \ J$ and to the snake is $4 \ J$.

In the following food chain,grass provides $4000 \ J$ of energy to the grasshopper. How much energy will be available to the snake and the frog? Grass $\rightarrow$ Grasshopper $\rightarrow$ Frog $\rightarrow$ Snake.
