Question

how does biomass change from lower to higher trophic levels? (1 point) it decreases. it fluctuates. it increases. it stays the same.

Explanation:

Ecological trophic levels follow the 10% rule, where only ~10% of energy (and thus biomass) transfers from one level to the next. Most energy is lost as heat or used for organism functions, so total biomass gets smaller at each higher trophic level.

Answer:

It decreases.
