Are consumers found at the top or bottom of an energy pyramid? Explain your answer.

Consumers tend to be towards the top because they rely on producers for their energy. Producers have unlimited energy from the sun, but consumers have a limited source and therfore transfer less energy.

How would other animals be affected by the disappearance of a tertiary consumer?

The secondary consumers eaten by the tertiary consumer would become overpopulated and leading to a disturbance in all levels of the energy pyramid. Secondary consumers would have little resources and primary consumers would suffer being hunted by the overpopulated secondary consumers.
