A primary consumer is an organism that feeds on producers (plants) in an ecosystem. They are the second trophic level in a food chain, following the producers. Primary consumers are also known as herbivores, as they mainly consume plants for their energy and nutrients.
By understanding the role of primary consumers in an ecosystem, we gain insights into the interconnectedness of living organisms and the flow of energy within ecological communities.
