Energy moves from producers to the first group of consumers who feed directly on plants. These first-level consumers are herbivores, feeding on producers, so they form the primary consumer level. They’re the organisms that obtain energy by eating the producers that captured energy from the sun. Higher levels—secondary and tertiary consumers—eat other animals, not plants, and decomposers break down dead material rather than feeding on living producers. So the organisms that eat producers belong to the primary consumer level.
