Why is an energy pyramid shaped like a triangle with the point on the top?

The energy decreases as you move through the trophic levels from the bottom to the top of the energy pyramid. This is because the energy is used up by the organisms at each level. The pyramid shape is used to represent the flow of energy because of the way that energy is used up and lost throughout the system.
