Which level of the pyramid has the least total stored energy?

Answer Details

The level of the pyramid with the least total stored energy is level H. This is because as you move up the pyramid from level A to level H, there is a decrease in the amount of energy available. This is due to the loss of energy as it is transferred from one trophic level to the next through various ecological processes, such as respiration, heat loss, and incomplete digestion. At each level, only a small fraction of the energy available at the previous level is passed on. Therefore, the higher up the pyramid you go, the less energy is stored. Level H is at the top of the pyramid, which means it has the least total stored energy.
