There are usually more prey compared to the predators that feed on them.
Which of the following statements explains this?

All of the energy stored in the prey is transferred up the
food chain

Predators need energy for cellular respiration but their
prey do not

Only some of the energy stored in the prey can be used
by the predators to stay alive

Hi! The answer is Only some of the energy stored in the prey can be used by the predators to stay alive.

Explanation:

Predators are fewer in number than prey because they are higher up the food chain. In a food chain, an organism passes on only part of the energy it receives from food. With less energy, each level in a food chain supports fewer individuals than the one below it.

Hope this helped!
