Vedclass · Answer

(A) In a food chain, energy is transferred from one trophic level to the next. According to the $10\%$ law of energy transfer, only about $10\%$ of the energy available at one trophic level is transferred to the next higher level.Due to this significant loss of energy, the amount of biomass and the number of organisms that can be supported decreases as we move to higher trophic levels.Therefore, the Assertion is correct because higher trophic levels have fewer organisms.The Reason is also correct because the population size at any trophic level is limited by the energy and food supply provided by the lower trophic level.Since the limitation of food/energy at lower levels directly causes the reduction in the number of individuals at higher levels, the Reason is the correct explanation of the Assertion.

Assertion : In a food chain, members of successive higher levels are fewer in number.
Reason : Number of organisms at any trophic level depends upon the availability of organisms which serve as food at the lower level.
