Question

assessment student answers how does energy move from one level to the next in this food pyramid? a all of the energy from producers moves to the primary consumers and then on up the pyramid b only some of the energy from each level moves up to the next higher level because energy is also transferred to the environment as heat c the flow of energy increases from one level to the next so that tertiary consumers receive the most energy from the levels below them d each level receives energy directly from the sun, but each level is less efficient at converting sunlight into usable energy

Explanation:

In an ecological food - pyramid, energy transfer is not 100% efficient. As energy moves from one trophic level to the next, a significant amount is lost as heat to the environment. Producers capture energy from the sun, and only a fraction of that energy is passed on to primary consumers when they eat the producers. Similarly, primary consumers pass on only some of their energy to secondary consumers.

Answer:

B. Only some of the energy from each level moves up to the next higher level because energy is also transferred to the environment as heat
