Take a candle and burn it. Take a glass and cover the candle. You will see the candle is slowly getting stopped. Ultimately, it will stop burning. But if you keep that candle in open air without enclosing it inside a glass, it will get free oxygen from air which will definitely help in its burning or combustion. So, Air, more specially, oxygen of air is necessary for combustion process.
