Vedclass · Answer

(D) The given sequence $10,000 \, J \rightarrow 1000 \, J \rightarrow 100 \, J \rightarrow 10 \, J$ represents the $10 \%$ law of energy transfer in an ecosystem.$1$. Unidirectional flow: Energy in an ecosystem flows in one direction,from producers to consumers,and is never recycled back to the source,which is consistent with the given data.$2$. $10 \%$ Law: According to Lindeman's $10 \%$ law,only $10 \%$ of the energy available at one trophic level is transferred to the next,while $90 \%$ is lost as heat or used for metabolic activities. In this sequence,each subsequent level retains exactly $10 \%$ of the previous level's energy.$3$. Applicability: This principle is a fundamental characteristic of all food chains,including grazing food chains.Therefore,option $A$ is correct regarding the flow,and option $B$ is correct regarding the energy transfer efficiency. Since both are true,the correct answer is $A$ and $B$ (though the provided option $D$ is the intended choice in this context).

$10,000 \, J \rightarrow 1000 \, J \rightarrow 100 \, J \rightarrow 10 \, J$
