Science Blog 4 (Class Response)

Consumers, Producers and Decomposers


What are producers, consumers, and decomposers? These terms indicate how organisms get its energy and how they interact/connect with the outside world. Consumers are organisms or heterotrophic that feed on plants or other animals (produced food by other organisms). There are three types of consumers: Herbivores, carnivores, and omnivores. Herbivores are organisms that eat only plants. Carnivores are organisms that feed on other animals. Omnivores are organisms that feed on both animals and plants. For example, humans are omnivores, lions are carnivores, and rabbits are herbivores. Producers are organisms that get a source of energy to make their own food. Therefore, decomposers are organisms that recycle nutrients from decaying organic materials. They are mostly fungi or bacteria. Decomposers break down abiotic/nonliving organic matter, into inorganic matter. Decomposers start a food chain and end it too. Overall, consumers, producers, and decomposers are terms that tell the differences in obtaining energy and interacting with other living organisms!
