No, although it is essential for a fire. In technical terms a fire needs two chemical ingredients: fuel and oxidizer. The fuel is whatever is burning, whether it is wood, gasoline, or methane. Oxygen is the oxidizer.
The three elements of the fire triangle that must be present are Heat, Oxygen, and Fuel. This has recently been changed though from the fire triangle to the fire tetrahedron. This includes Heat, Oxygen, and Fuel as well. But, it also contains a fourth, chemical reaction.
For fire you need three main ingredients. First you need a fuel, this fuel can be anything that burns like wood for example. Second you need oxygen, without oxygen a fire cannot burn. Finally you need heat, even though fires give off heat you still need it to start a fire. If you remove any one of these three ingredients then the fire will die.
The three components of fire are heat, fuel, and oxygen. Heat is required to ignite the fuel, while fuel provides the material that sustains the fire. Oxygen is necessary for the combustion process to occur.
When you remove fuel and oxygen from a fire, the fire will be extinguished. Fire requires fuel (such as wood or gas) and oxygen to continue burning, so removing either one will stop the combustion process.
The three factors needed for a fire are heat, fuel and oxygen. Note that these are not elements in the chemical sense. (Oxygen is, but most fuels are compounds or mixtures, and heat is energy, not matter.)
If you remove fuel, oxygen, or both from a fire, the fire goes out.

Fuel, oxygen and heat or an ignition source are the components needed for a fire.
it is Oxygen, heat, fuel. the fire triangle is just a short saying for all these elements
