An omnivore (/ ˈɒmnɪvɔːr /) is an animal that has the ability to eat and survive on both plant and animal matter. Obtaining energy and nutrients from plant and animal matter, omnivores digest carbohydrates, protein, fat, and fiber, and metabolize the nutrients and energy of the sources absorbed.

An omnivore is any animal that is a generalist feeder, consuming a wide variety of foods that include both animal and plant matter. Omnivores may assume diverse roles within ecological food webs, acting as primary consumers when eating plant material or acting as a much higher-level consumer when eating meat.
