Fire feeds on oxygen. The atmosphere is composed of oxygen, carbon dioxide, etc. etc. If the fire eats all of the oxygen, all that's left is carbon dioxide. The carbon dioxide doesn't make it go out, it's just the end-product. The lack of oxygen is what leads the fire to die.

As the first person said it is the absence of oxygen. Carbon Dioxide will make it go out simply because it contributes to the absence of oxygen.

Answer 5

It is the lack of oxygen. Fire needs oxygen to burn. That's why covering up a candle puts it out.
