heterotroph

an organism dependent on obtaining organic food from the environment because it is unable to synthesize organic material. All animals, fungi, many bacteria, plants without chloroplasts and a few flowering plants (such as insectivorous plants) are heterotrophs, and they obtain almost all their organic material, either directly or indirectly, from the activity of AUTOTROPHS. See HOLOZOIC, SAPROPHYTE, PARASITE.
