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.

Some heterotrophs do not seem to respond to any of the compounds tested so far; others will grow much faster and reach a higher concentration when given compounds from certain autotrophs, but not others.
A key to my research is that autotrophs and heterotrophs each prefer to use a different form of carbon.
An observation of different signatures would suggest that researchers utilizing stable isotopes to investigate chemosynthetic usage by heterotrophs should consider the signature of chemosynthetic sites near the area of capture as a better tracer signature than those further away.
Yet many believe that heterotrophs evolved before autotrophs, which makes the autotroph drooling even harden to justify.
