A food chain shows how organisms get their food. A food chain starts with plants or producers. Producers make there own food. The second organisms in a food chain are the consumers. There are three types of consumers. The three types are omnivores, herbivores, and carnivores. An omnivore is an organism that eat both plants and other organisms. An herbivore is an organism that eats only plants. A carnivore is an organism that eats only other organisms. Carnivores are also pedators. Pedators are animals that eat other animals for food. Omnivores are also pedators. The animal that is eatin by a pedators is prey. Prey is an animal that is eaten by pedators. At the end of the food chain are decomposers. Decomposers are organisms that eat dead or decaying plants or organisms. Decomposers are usually bacteria or fungi. Here is an example of a food chain.
