Why are there largely a larger number of producers than tertiary consumers in an ecosystem? A. Only about half of the energy passes on to the next organism in a food chain, so there needs to be more of the living things lower in the energy pyramid to support the living things higher in the pyramid.

B. All of the energy is passed from level to level in the energy pyramid, so the number or tertiary consumers is always higher.

C. Only about 10% of energy is passed on to the next organism in a food chain, so there needs to be more of the living things lower in the energy pyramid to support the living things higher in the pyramid.
