Question

Which statement is most appropriate?

• A. The biomass in each trophic level is lesser than that of the trophic level below in a terrestrial ecosystem.
• B. The biomass in each trophic level is always lesser than that of the trophic level below
• C. The biomass in each trophic level is always more than that of the trophic level below
• D. None of these

Answer 1

The correct option is A The biomass in each trophic level is lesser than that of the trophic level below in a terrestrial ecosystem.

Pyramids of biomass can be both inverted as in an aquatic ecosystem or upright as in a forest ecosystem. But, upright pyramids of biomass are usually seen in terrestrial ecosystems. Therefore, it is most appropriate to say that biomass in each trophic level is usually less than the trophic level below in a terrestrial ecosystem.
