Carnivore

A Carnivore is an organism (usually animals or some plants) that must eat animals through predation or scavenging. They are consumers, more specified as second level or higher leveled consumers. This is a picture of my dog but dogs are carnivores since even though some have been domesticated to eat plants, (or other not meaty foods) naturally they eat strictly meat just like their close cousins the wolves and foxes.
