Cellular respiration is the metabolic reaction inside the cell to convert chemical energy into ATP. Biomass is the total mass of organisms at a trophic level.
<h3>What is exothermic reaction?</h3>
The type of reaction in which releases energy after its completion.
- Cellular respiration releases energy because it is an exothermic process in which energy is released as a by-product of the reaction.
- Organisms are larger in size at higher trophic levels, but their smaller numbers result in less biomass.
Thus, being exothermic in nature, cellular respiration releases energy and because of less numbers, there is less biomass at high trophic levels.
