1 Answer

Answer :

At each trophic level in a food chain, a large portion of theenergy is utilized for the maintenance of organisms which occur atthat trophic level and lost as heat. As a result of this, organismsin each trophic level pass on less and less energy to the nexttrophic levels, than they receive.
