For any natural ecosystem, which of the following statements applies to the energy pyramid, the biomass pyramid, and the numbers pyramid?

Question

Producers are at the bottom level of all three pyramids.

Consumers form the bottom levels, while producers are at the top.

Consumers are at the bottom of the energy pyramid, only.

Producers are at the bottom of the energy and biomass pyramids, only.

Answer 1

The correct statement is:

Producers are at the bottom level of all three pyramids.

In an energy pyramid, biomass pyramid, and numbers pyramid, producers (such as plants) occupy the base because they generate energy through photosynthesis, which supports all other levels of consumers (herbivores, carnivores, etc.) in the ecosystem.
