Ques: Answer the following question given this paragraph: With less energy at higher trophic levels, there are usually fewer organisms as well. Organisms tend to be larger in size at higher trophic levels, but their smaller numbers result in less biomass. Biomass is the total mass of organisms at a trophic level. The decrease in biomass from lower to higher levels is also represented by Figure above . Q: Organisms tend to be larger in size at higher what levels? Choices: - proteolytic - benthic - Secondary Layer - trophic A:
Ans: trophic
