Consumers in biology are organisms that rely on other organisms for sustenance. Examples of consumers include herbivores, carnivores, omnivores, and detritivores. Consumers can also be grouped into primary consumers, which feed directly on producers, and secondary consumers, which feed on primary consumers. Consumers play an important role in the food chain, as they transfer energy between trophic levels, and some consumer species also help to control population sizes and maintain species diversity.
