The term for animals that are exclusively herbivores is "herbivorous." Herbivores primarily consume plant-based foods, including leaves, stems, fruits, and roots, and they play a crucial role in maintaining ecological balance. Various adaptations characterize herbivores, such as specialized teeth for grinding and chewing plant material, along with longer digestive systems to break down cellulose found in plant cell walls. Common examples of herbivorous animals include cows, deer, and elephants. They contribute to plant population control, seed dispersal, and serve as prey for carnivorous animals in the food chain.
