Question

drag and drop the words into the correct locations. (2 points)
only about _ (1) of the energy stored in one trophic level is transferred to the next level. most of the remaining energy is lost as _ (2) during metabolic processes. because of this energy loss, higher trophic levels have less available ___ (3)
options: nutrients, 90 percent, heat, population size, biomass, 10 percent

Explanation:

1. The 10% rule in ecology states only ~10% of energy transfers between trophic levels.
2. Metabolic processes release most unused energy as heat.
3. Energy loss means higher trophic levels have less available biomass, as biomass is tied to stored energy.

Answer:

(1) 10 percent
(2) heat
(3) biomass
