Answer:
Fire is a chemical reaction in which energy in the form of heat is produced. When forest fuels burn, there is a chemical combination of the oxygen in the air with woody material, pitch and other burnable elements found in the forest environment. This process in known as Combustion.
Combustion, however..... start with carbon, and oxygen C(s)+O2(g) , and end up with carbon dioxide CO2(g) a completely different molecule - that's a chemical change.
