Which trophic level (producer/1st/2nd/3rd order heterotroph) has the most energy? explain where their energy comes from and how they utilize this energy source.

1st trophic level

explanation:

the farther in the levels the less energy for example if the first trophic level has 10,000 then the next will have 1,000 then 100

all fossil fuels are nonrenewable, so think coal, gasoline, things that we will eventually run out of. all fossil fuels are nonrenewable resources, but not all nonrenewable recourses are fossil fuels. these resources are not being renewed as fast as we are using them. i hope this considering there weren't any answer choices.
