What is energy?

Detailed explanation-1: -Key Points. Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.
Detailed explanation-2: -As you move up the pyramid, through the trophic levels to primary, secondary and tertiary consumers, the amount of energy decreases and the levels become smaller. While energy can not be created or destroyed is it released as heat within each level. Approximately only 10% of energy is passed from one level to the next.
Detailed explanation-3: -Q. Which statement best describes the flow of energy as it passes through the organisms in the pyramid? Energy flows through the organisms from bottom to top and increases at each level.
Detailed explanation-4: -Answer and Explanation: The energy transfer between trophic levels is best described as inefficient. Plants and other producers can only use about one percent of the energy that reaches Earth from the sun. With each subsequent trophic level the amount of energy is further reduced.
Detailed explanation-5: -Thus, the correct answer is ‘Bioenergetics. ‘
