What term is used for animals that exclusively feed on plants?

The term used for animals that exclusively feed on plants is "herbivore." Herbivores are a crucial part of the ecosystem, as they play an integral role in the food chain. By consuming plant material, herbivores facilitate the transfer of energy from the primary producers (plants) to higher trophic levels, such as carnivores and omnivores.

Herbivores have specialized adaptations that help them efficiently digest plant material, which is often tough and fibrous. These adaptations can include specialized teeth for grinding, a longer digestive tract to break down cellulose, and symbiotic relationships with gut microbes that assist in digesting plant matter.

Understanding the role of herbivores in ecosystems highlights their importance in maintaining biodiversity and the balance of various habitats, as they contribute to plant population control and the overall health of the ecosystem.
