Vedclass · Answer

(A) The number of trophic levels in a food chain is limited by the $10\%$ law of energy transfer. According to this law,only about $10\%$ of the energy available at one trophic level is transferred to the next higher trophic level. The remaining energy is lost as heat during metabolic activities. As a result,after $3$ to $4$ trophic levels,the amount of energy remaining is insufficient to support the survival of organisms at the next level. Therefore,the decrease in energy at higher trophic levels acts as a limiting factor.
