Grass-eating animals are commonly referred to as herbivores. These animals feed on plant material such as grasses, leaves, and fruits. Other synonyms for grass-eating animals include grazers, browsers, and folivores. Grazers are animals that consume predominantly grasses, while browsers feed on the leaves and twigs of shrubs and trees. Folivores eat primarily foliage and leaves. Examples of grass-eating animals include cows, sheep, horses, and goats, while deer, giraffes, and elephants are examples of browsers. Herbivorous animals play a vital role in maintaining the balance of nature by helping to control the growth of plants and vegetation in ecosystems.
