Answer:
A photoautotoph is an organism which converts light energy from the sun into chemical energy.
Step-by-step explanation:
Energy which is stored in the chemical bonds of chemical compounds is called chemical energy.Chemical energy is released during the occurrence of chemical reaction.Reactions wherein energy is given out in the form of heat is called exothermic reactions.
Chemical energy can be converted to other forms of energy like electrical energy during the process of electrolysis and to thermal energy as in the case of thermal engines.
It can also be converted to kinetic energy during explosions . It is stored in batteries, coal, biomass, food, vehicle air bags,etc.Digestion of food is also an example of conversion of chemical energy .It is utilized during the process of photosynthesis.
