Which statement provides the best explanation for the difference in biomass of organisms found at each trophic level?

• Organisms at higher trophic levels have less energy available to them than organisms at lower trophic levels.

• Organisms at higher trophic levles require smaller habitats than organisms at lower trophic levels.

• Organisms at lower trophic levels provide less energy than organisms at higher trophic levels.

• Organisms at lower trophic levels outcompete organisms at higher trophic levels.
