Detailed explanation-1: -The top level of an energy pyramid has the fewest organisms because it has the least amount of energy.
Detailed explanation-2: -Electrons in energy level I (also called energy level K) have the least amount of energy. As you go farther from the nucleus, electrons at higher levels have more energy, and their energy increases by a fixed, discrete amount.
Detailed explanation-3: -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-4: -Identify and describe the levels of the pyramid: producers, primary consumers, secondary consumers, tertiary consumers. Understand the role of decomposers.
