Question

why is there less energy in the top of the energy pyramid than there is in the bottom of the energy pyramid?

Answer 1

Less energy is available to the organisms in the upper levels because each organism releases some of the chemical energy in food to the air as thermal energy. Less total energy is available with each step up the energy pyramid.

*Not my own words but it’s the right answer*

Answer 2

Because at each trophic level energy is wasted or released into the environment.

Step-by-step explanation:

Energy transfer from one organism to another is not complete transfer.Some energy goes into the environment in some other form.
