I have been asked this question during an internship interview.

The question is from Ecological Pyramids in chapter Ecosystems of Energy Management

Answer 1

The correct choice is (b) The biomass in each trophic level is always less than the below trophic level

Explanation: Biomass is a measure of the amount of food available. When animals eat only a small proportion of their food, it is converted into new tissue. This tissue is the food for the next trophic level organisms.
