Which trophic level contains more energy: a trophic level of herbivores or a trophic level of carnivores? Why?
Bas_tet [7]
Hello :)

The answer to your question is a trophic level of carnivores


Only a fraction of the energy available at one trophic level is transferred to the next trophic level.

Since carnivores are above herbivores in the trophic levels, herbivores have more energy than carnivores.

Hope this helps and have a great day!
