Question

Why are the levels at the top smaller and the ones on the bottom larger in the energy pyramid? HELP ASAP

Answer 1

Because as each organism goes up, there's less energy being given. Here's an example.

Take a plant, it has 100% of its energy. Then it's eaten by a deer, which could be the Primary Consumer. The deer has 10% of the beginning energy. Then, the deer is eaten by a wolf, a Secondary Consumer, which then has 1% of the energy.
