Answer 1

The correct response is:

The amount of energy available for use by the next organisms decreases going up from one level to the next.

In an energy pyramid, only about 10% of the energy from one trophic level is transferred to the next level (this is known as the 10% rule). As a result, there is less energy available for organisms at higher levels, which limits the number of levels that can be supported in a food web or energy pyramid.
