Difference between autotrophs and heterotrophs

Autotrophs are those that produce food on their own. Examples of Autotrophs are plants. They produce food on their own from the use of Sunlight, Water and Minerals through Photosynthesis, while Heterotrophs are those that do not produce food on their own. Animals and us, Humans, are Heterotrophs. We need to hunt or grow vegetables in order to eat.
