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.
Autotroph: Autotroph, in ecology, an organism that serves as a primary producer in a food chain. Autotrophs obtain energy and nutrients by harnessing sunlight through photosynthesis (photoautotrophs) or, more rarely, obtain chemical energy through oxidation (chemoautotrophs) to make organic substances from inorganic ones. Autotrophs do not consume other organisms; they are, however, consumed by heterotrophs.
