Phototrophs and chemotrophs are two types of nutritional groups found in the environment. Most phototrophs are autotrophs, using the energy from sunlight to produce their food. Chemotrophs oxidize inorganic compounds or organic compounds as their energy source. They are the primary producers of food chains. The main difference between phototrophs and chemotrophs is that phototrophs capture protons in order to acquire energy whereas chemotrophs oxidize electron donors in order to acquire energy.
