A food chain, which shows part of a food web, can have an animal that eats only plants (herbivore). It can have an animal that eats only other animals (carnivore). It can also have an animal that eats both plants and animals (omnivore). An animal can hunt animals to get its food (predator). An animal can be hunted by another animal for food (prey).
