Herbivores are animals that primarily consume plant material. Their diet consists of leaves, stems, fruits, and seeds. Herbivores possess specialized digestive systems that allow them to break down tough plant fibers, enabling them to extract the necessary nutrients from their food. Common examples of herbivores include cows, horses, giraffes, and rabbits. Some herbivores, like cows, possess a ruminating stomach that aids in the fermentation and breakdown of plant material, allowing for efficient digestion and nutrient absorption.
