Is oxygen needed for combustion?
Combustion is an exothermic reaction that occurs between a fuel and an oxidizer, which is oxygen.
Combustion occurs when the fuel (substance with energy potential) is oxidized by the action of the oxidizer (usually atmospheric air or oxygen gas), producing energy in the form of heat.
With this information, we can conclude that One of the roles of oxygen in Earth's atmosphere is to allow fuels to burn.
