In the trophic level pyramid above, what segment represents the placement of a herbivore?

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!
