Based on how organisms get their energy, they are divied into two groups: autotrophs and heterotrophs. First of all, Autotrophs are very important and without them a lot of species would die. They are able to make organic molecules from inorganic material by using the energy of the sun. Plants are a perfect example of this when they use photosynthesis. Organisms that get their food from other organism are called heterotrophs. An example of this is shown in my picture: a buny(heterotroph) getting its energy from a flower(autotroph) that gets its energy from the sun. (Nave, 1985)
