Energy Pyramid

Sun's Energy

living organisms consume the energy that is obtained by the lower trophic level

decomposers consume energy at each trophic level

higher trophic levels cannot access energy from the sun

a lot of energy is released to the environment at heat

Correct answer: living organisms consume the energy that is obtained by the lower trophic level

As energy is transferred from one trophic level to the next, much of it is lost as heat or used for metabolic processes, resulting in a decrease in the amount of energy available at each successive trophic level. This is why the percentage of energy contained in each successive trophic level decreases by about ninety percent.
