Answer:
A. Ants
Explanation:
Herbivorous animals are those that consume live plants or part of them. In this way, ecologically speaking, they can play a role as predators, by removing individuals from the population; or parasites, for consuming certain plant structures, but without killing them. Accordingly, we can say that herbivores can eat algae, ferns and leaves, but do not feed on ants.
Considering these facts, herbivores are able to control some plant populations by reducing their growth and reproduction rates. For this reason, some insects with this feeding habit are used to control the growth of plantation pests.
