What term is used for animals that only eat plants?

Herbivores are defined as animals that primarily consume plants. This classification includes a diverse range of species, from large mammals like elephants and cows to smaller creatures such as rabbits and various insects. The digestive systems of herbivores are specifically adapted to efficiently process plant material, which can be difficult to break down due to its cellulose content.

In ecosystems, herbivores play a crucial role as primary consumers, forming the second tier in the food chain after producers (plants) and serving as a vital source of energy for carnivores, which are organisms that eat other animals. The understanding of herbivores is essential in ecological studies, as it relates to the larger concepts of habitat dynamics, energy transfer, and ecosystem balance.
