A herbivore is an animal that eats plants. 1) Some herbivores, especially seed eaters (granivores), act like predators in that they totally consume the organism. 2) Other animals, such as those that eat grasses (grazers) or leaves of other plants (browsers), may eat only part of the plant but may we ...

Herbivore
_grazing_-_20050809.jpg?width=300)
A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage, for the main component of its diet. As a result of their plant diet, herbivorous animals typically have mouthparts adapted to rasping or grinding. Horses and other herbivores have wide flat teeth that are adapted to grinding grass, tree bark, and other tough plant material.
