Basically, a heterotroph is a consumer which must eat other animals and cannot produce its own food.
This contrasts with autotrophs, such as plants, algae and  some bacteria, that can use energy from sunlight (photosynthesis)  or inorganic compounds to produce organic compounds such as  carbohydrates, fats, and proteins from inorganic carbon dioxide.   Humans are a good example of heterotrophs.These reduced carbon compounds can be used as an energy source by  the autotroph and provide the energy in food consumed by  heterotrophs. More than 95% of all organisms are heterotrophic.[2]   A heterotroph is an organism that requires organic  substrates to get its carbon for growth and development.
