Question

which statement best describes the flow of energy through this pyramid? a. secondary consumers represent the most organisms, and they have the greatest amount of energy in their trophic level. b. tertiary consumers do not receive all the energy from the trophic level below them, because some energy is lost to the environment. c. primary consumers transfer energy to the trophic level above them and the trophic level below them.

Explanation:

In an energy - pyramid, energy is lost as it moves up the trophic levels. Tertiary consumers (frogs in this case) are at the top. They don't receive all the energy from the level below (aquatic insects) because energy is dissipated to the environment at each transfer. Secondary consumers don't have the most energy or the most organisms. Primary consumers transfer energy only to the level above them.

Answer:

B. Tertiary consumers do not receive all the energy from the trophic level below them, because some energy is lost to the environment
