Stepped Art Energy, Producers, and Consumers sunlight energy A Producers harvest energy from the environment. Some of that energy flows from producers to consumers. Producers plants and other self-feeding organisms Consumers animals, most fungi, many protists, bacteria B Nutrients that become incorporated into the cells of producers and consumers are eventually released by decomposition. Some cycle back to producers.
