The correct response is:
Because 10% of the energy at each level moves to the next level and some additional energy is converted to heat.
In an energy pyramid, energy is transferred from one trophic level to another, but only about 10% of the energy from the level below is passed on to the next level. The rest is lost as heat due to metabolic processes and other factors. This is why each successive level is smaller than the one below it.
