CONSUMERS get energy by eating other organisms - herbivores: eat producers - carnivores: eat other consumers - omnivores: eat producers and consumers - detritivores: feed on “garbage” or dead organic matter - decomposer: break down dead organic matter into simpler molecules  Recycle nutrients back into ecosystem
