If you mean hetrotroph, it means:
An organism that is unable to synthesize its own organic carbon-based compounds from inorganic sources, it insteads feeds on organic matter by, or avaliable in, other organisms.
Humans are an example of a heterotroph, a flower is not an example.
An organism that can not produce its own food and must consume other organisms, whether plant or animal, is heterotrophic.
