The correct sequence of trophic levels in a food chain is producers, primary consumers, secondary consumers, and tertiary consumers. Autotrophs are organisms that can produce their own food, while heterotrophs are organisms that cannot produce their own food and must consume other organisms to obtain energy. Decomposers are organisms that break down dead organisms and recycle their nutrients back into the ecosystem. Omnivores are organisms that eat both plants and animals, carnivores are organisms that eat only animals, and herbivores are organisms that eat only plants.
