D) less than the biomass of E

Quizplus · Accepted Answer

In a food chain, biomass decreases as you move up the trophic levels. Therefore, the combined biomass of C + D (which are at a higher trophic level) would be less than the biomass of A + B (which are at a lower trophic level). The biomass of E is not comparable to C + D as they are not directly linked in the food web.
