The main difference between autotrophic and heterotophic cells is  that autotroph cells produce their own food, while heterotrophic  cells do not. Another difference is that â¦ autotrophs obtain carbon  from inorganic sources like carbon dioxide, while heterotrophs get  their reduced carbon from other organisms.
Autotrophs are self feeders that use light or chemical energy to make food. Plants are an example of autotrophs. In contrast, heterotrophs (other feeders) obtain energy from other autotrophs or heterotrophs. Many bacteria and animals are heterotrophs.
