Why is the energy pyramid not a smooth geometric shape like a triangle but, rather, looks like narrow blocks stacked on top of wider blocks?(1 point)
Responses
A triangular pyramid would reflect a food pyramid rather than energy flow.
Energy decreases at each level, and only 10% remains from the previous level.
Lower levels have far more individuals, so the shape reflects their population size.
The sizes of each shape show how much is consumed (or produced) at each level.
The correct answer is:
Energy decreases at each level, and only 10% remains from the previous level.
The energy pyramid is not a smooth geometric shape like a triangle because energy decreases as you move up the pyramid. Each level of the pyramid represents a trophic level in an ecosystem, and only about 10% of the energy is transferred from one level to the next. As a result, the blocks in the energy pyramid become narrower as you move up, representing the diminishing energy available at each trophic level.
