In nature, we find a wide range of animals with diverse dietary habits. An interesting group within this diversity are herbivores, animals that feed mainly or exclusively on plant material. These animals play a critical role in ecosystems around the world.

What are herbivores?

Herbivores are animals that feed on plants. This includes a wide range of foods such as grass, leaves, fruit, flowers, bark, and seeds. These animals often have special adaptations in their digestive system that enable them to effectively digest plant material and extract nutrients from them.
