Question

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

Answer 1

The energy pyramid is one type of graphical representation of ecological relationships that is in the shape of a pyramid. The base must have the largest amount of biomass (shown as the widest bar) so it can support the energy requirements of the organisms at higher levels. Each higher level in the pyramid gets smaller (the bars get narrower) because only about 10% of the available energy transfers to the next level. The shape of the energy pyramid shows that there is enough biomass energy contained in the primary producers at the bottom to support the predators at the top, even though energy is lost at each level.

Step-by-step explanation:

Answer 2

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.
