The term for animals that only eat plants is herbivores. Herbivorous animals have evolved specialized digestive systems for breaking down plant material, which is often tough and fibrous. Common examples of herbivores include cows, deer, rabbits, and elephants. They play crucial roles in their ecosystems by aiding in seed dispersal, controlling plant populations, and serving as prey for carnivorous animals. Some herbivores may graze on basic foliage, while others may prefer fruits, roots, or grains. Overall, herbivores are essential for maintaining ecological balance and contributing to biodiversity.
