Because about 10% of the energy is converted to heat when organisms become ill and another 10% when they die.
Because 90% of the energy is passed on to the next level to be used by the organisms there.
Because the sizes of each level show that 10% is consumed by organisms at that level.
Because 10% of the energy at each level moves to the next level and some additional energy is converted to heat.

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 energy pyramids, typically only about 10% of the energy from one trophic level is passed on to the next level, while the rest is lost as heat or used for metabolic processes. This is why each successive level of the pyramid is smaller.
