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.
An autotroph or producer, is an organism that produces complex organic compounds from simple substances present in its surroundings, generally using energy from light or inorganic chemical reactions. They are the producers in a food chain, such as plants on land or algae in water. They do not need a living source of energy or organic carbon. Autotrophs can reduce carbon dioxide to make organic compounds for biosynthesis and also create a store of chemical energy. Most autotrophs use water as the
