Heterotroph
An organism which is unable to synthesize and fix its own organic carbon-based compounds.[1] They obtain their energy from chemical fuels, and therefore depend heavily on autotrophs. [2] They can be separated into sub-sections according to how they obtain their energy; if the organism uses Chemical energy then it is called a chemoheterotroph, contrasted to an organism using light energy which is named a photoheterotroph.
