What is an autotroph and what is a heterotroph

Autographs are organisms that make their own food/energy. The only example I can think of (and the only one I think exists) is plants. They make glucose from the sun and other stuff

Heterotrophs are organisms that needs to get its energy from other sources. You and me are heterotrophs (well unless you are a plant lol). We have to eat food to get energy to survive.

Hope this helped!!!

An heterotroph is an organism deriving its nutritional requirements from complex organic substances.
