Depends on the plant. Grasses' growth point is at soil level. So if the animal doesn't not eat all the way to the ground, but leaves the grass growth plate, the grass will simply grow more blades providing it was not grazes excessively preventing energy storage by the plant to grow more.

Relationships between herbivores and their host plants often results in reciprocal evolutionary change, called co-evolution. When an herbivore eats a plant it selects for plants that can mount a defensive response. In cases where this relationship demonstrates specificity (the evolution of each trait is due to the other ), and.
Plants respond to herbivory through various morphological, biochemicals, and molecular mechanisms to counter/offset the effects of herbivore attack. The biochemical mechanisms of defense against the herbivores are wide-ranging, highly dynamic, and are mediated both by direct and indirect defenses. The defensive. Start studying Botany- Lecture Plant responses to other environmental stimuli. Learn vocabulary, terms, and more with flashcards, games, and other study tools. If herbivores breach a plant's barriers, the plant can respond with secondary metabolites, which are often toxic compounds, such as glycol cyanide, that may harm the herbivore.

Studies of the mechanism by which insects induce plant response have led to the discovery of fatty acid–amino acid conjugates (FACs) in herbivore oral secretions that elicit herbivory-specific responses, such as JA and ET bursts, that are greater than those elicited by mechanical wounding; high levels of trypsin proteinase.
