Introduction:

All the living organisms differ in the way of acquiring energy. They adopt different strategies and methods. The organisms that use the energy of the sun for biological reactions are autotrophs. They are of different types: chemoautotroph and photoautotroph. Few organisms use other organisms for fulfilling their energy requirements. These are called heterotrophs. Heterotrophs can be chemoheterotroph or photoheterotroph.
