Definitions for "Omnivore"
A plant and flesh eater.
An organism that eats both plants and animals.
An animal that eats both plant material and the flesh of other animals. This is thought to be more common than was previously realised, and is probably a response to a seasonal lack of food, or a requirement for a specific nutrient. Most obvious omnivorous animals have teeth that are capable of processing different types of food - they have large molars like herbivores so that they can grind up plant material, but they also have sharp incisors and canine teeth so that they can slice meat. Humans are omnivores.
