Question

Why are there more herbivores than carnivores in an ecosystem?

Answer 1

Carnivores are at a higher trophic level than Herbivores, and producers (plants) are at a lower trophic level than Herbivores. At each successive trophic level, only 10% of the energy is passed.

Explanation:

This means that from producers to herbivores, 10% of energy is passed, and from herbivores to carnivores also 10% of the energy is passed. It has to do with the second law of thermodynamics.
