How does biomass change from lower to higher trophic levels?

Question

A. It increases
B. It stays the same
C. It fluctuates
D. it decreases

Answer 1

D. it decreases

Biomass generally decreases from lower to higher trophic levels due to the transfer of energy being inefficient. As energy moves up the food chain through trophic levels, a significant amount of energy is lost as heat through metabolic processes, and only about 10% of the energy is typically transferred to the next trophic level. This results in a decrease in biomass at higher trophic levels.
