The substances which undergo combustion are called combustible substances.
When a magnesium ribbon burns, it combines with oxygen of air to form magnesium oxide, and liberates heat and light. During this process of combustion, magnesium is a combustible substance.
If we hold a piece of charcoal with a pair of tongs and heat it on the flame of a burner, it starts burning to form carbon dioxide. In this process a lot of heat is produced but only a little light is produced.
In both the examples oxygen is necessary for combustion to take place. Air is the supporter of combustion because it contains oxygen.
