Consumer-decomposer a consumer is an organism that obtains its energy by feeding on other organisms a decomposer is an organism that obtains energy from the breakdown of dead organic matter to more simple substances. Herbivore-carnivore-omnivore herbivore is an organism that feeds on plant tissue a carnivore is an organism that feeds on animal tissue an omnivore is an animal that feeds on both plant and animal tissues.
