Producers,Consumers, and Decomposers

What are producers, consumers, and decomposers? These three terms indicate how an organism gets its energy and interacts with the other living things in its community. Producers are organisms that use a source of energy to make their own food. However, consumers are organisms that cannot make their own food. Therefore, they feed directly or indirectly on producers and depend on them for food and energy. In this category, there are three types of consumers. The three kinds are herbivores, carnivores, and omnivores. While herbivores only eat plants and leaves, carnivores only eat meat. However, the kind that eats both plants and meat is called an omnivore. Humans for example, are omnivores. Deers are herbivores and lions are carnivores. Besides producers and consumers, we also have decomposers in our ecosystem. Decomposers are organisms that break down dead matter into simpler substances. Bacteria and mold are two examples of decomposers. Also, along with breaking down dead matter, decomposers also start and end every food chain. In conclusion, producers, consumers, and decomposers are three terms that tell how different organisms obtain energy and interact with other living things in their community.
