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.
Heterotrophs contrast with autotrophs, such as plants and algae, which can use energy from sunlight (photoautotrophs) or inorganic compounds (lithoautotrophs) to produce organic compounds such as carbohydrates, fats, and proteins from inorganic carbon dioxide.verview of cycle between autotrophs and heterotrophs. A heterotroph (/ËhÉtÉrÉµtroÊf/ ; á¼ÏÎµÏÎ¿Ï heteros = another, different and ÏÏÎ¿ÏÎ® trophe = nutrition) is an organism that cannot fix carbon and uses organic carbon for growth.
