Herbivores are animals that primarily eat plants. They have special adaptations, like flat teeth, which help them grind leaves, stems, and roots. Common examples of herbivores include cows, deer, and rabbits. These animals play a crucial role in their ecosystems by helping to control plant growth and providing food for carnivores. Many herbivores have unique digestive systems to break down tough plant materials. For instance, cows have multiple stomachs that help them digest grass efficiently. Herbivores are essential for maintaining the balance of nature, as they contribute to the food chain and support various habitats.
