Herbivory
... Induced defenses (both physical, and chemical) are facultative defenses that are strengthened in proportion to consumption of plant material by herbivore (e.g., oaks increase production of tannins in response to herbivory; browsed Acacia depranolobium trees in Kenya have longer thorns than unbrowsed ...

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.
