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.
This is exactly what autotrophs do. Autotrophs are self-feeders, and they get their energy from non-living sources such as the sun and carbon dioxide. Autotrophs are called producers because they provide energy and food sources for all heterotrophic organisms. Types of Autotrophs. There are two types of autotrophs: photoautotrophs and chemoautotrophs.
