Producers, Consumers, and Decomposers Every food chain begins with a food producer. Oak trees and other green plants are food producers. They use energy in sunlight to make food. They cannot make their own energy.
They get energy by consuming eating other organisms. Some consumers eat plants. They are called herbivores plant eaters. Some consumers eat herbivores. They are called carnivores meat eaters. Some carnivores, such as hawks, eat other carnivores. One more group needs to be added to food chains. These are the decomposers. They feed on wastes from other organisms.
They also eat the remains of dead plants and animals. Decomposers include insects, worms, bacteria, and fungi. They play a very important role in a community. As they feed on dead matter, they break it down into simple chemicals. These chemicals are returned to the soil or the water. The chemicals become available to plants and algae, which use the chemicals to produce new growth. The Web of Life A food chain usually has about six links.
But most animals eat more than one kind of food and therefore are in more than one food chain. The food chains within a community are often connected and related. This network, or combination of food chains, is called a food web. Scavengers and Predators Sometimes there are special relationships between the members of a community. Some of the consumers are predators—they kill prey for food.
Eagles, owls, wolves, and humans are predators. Predators are usually well suited for catching, killing, and eating their prey. They have keen senses of sight, smell, or hearing. They can detect other animals from far away. Many predators can move quickly to catch a fleeing creature.
Some animals are scavengers. Scavengers eat the bodies of animals that have died or have been killed. In this way they return the materials of the dead animals to the food cycle. Vultures and jackals are scavengers. Symbiosis Different species in a community may live together in special relationships, called symbiosis.
