The oxygen that a fire needs is used to support the chemical reaction which takes place when something burns. The oxygen is used along with heat to convert the fuel, which typically is composed of hydrocarbons, to mostly carbon dioxide and water. Without the oxygen the fire would die out, because the chemical reaction couldn't take place without it. A fire needs three things in order to remain burning: fuel, an adequate supply of oxygen, and a sufficient heat source.
Oxygen does not itself burns but supports burning.If the burning substance does not get adequate amount of Oxygen the burning of a substance willl b reduced and fire wouldn't rise much.It will blowed off.
Fire requires oxygen because it is a key part of the chemical reaction that takes place during combustion. The oxygen reacts with the fuel source (such as wood or paper) and releases energy in the form of light and heat. Without oxygen, the chemical reaction cannot occur, and fire cannot be sustained.
Fire is a chemical reaction between oxygen and some flammable substance. For example, when you burn methane, the main component of natural gas the equation is:
CH4 + 2O2 --> CO2 + 2H2O
It is like Humans we need it to breath so it is like the same concept for them if you get me.
But it leads onto another question....
Why is the sun burning when there is no oxygen in space?
Yes. Fire needs three things to exist: Heat, Fuel and Oxygen (known collectively as the fire triangle).
oxygen is part of the burning reaction CxHy +zO2--> H20 +CO2 + CO + fire
The oxygen that a fire needs is used to support the chemical reaction which takes place when something burns.

What do you need to start a fire?
To start a fire, you will need fuel (such as wood or paper), a spark (from matches, a lighter, or a fire starter), and oxygen. It's important to have a safe and controlled environment to prevent the fire from spreading uncontrollably.
What 4 things are needed for a fire?
For a fire, you need fuel (such as wood or paper), oxygen (from the air), heat (from a spark or flame), and a chemical reaction (between the fuel and oxygen) to sustain the fire.
Do sparks need oxygen?
Sparks themselves do not need oxygen. However, for a spark to ignite and sustain combustion, oxygen is usually needed as it is one of the components required for fire.
What is needed for fire to burn?
In order for fire to burn, there is someting called the fire tetrahedron. The things needed for fire to burn are as listed: Heat, Oxygen, Fuel(of any sort), and a Chmeical Reaction with all of the above. I learned this from the multiple firefighting classes i have taken.
What are the three essential elements for a fire to occur?
you need an hydrocarbon of some form to act as fuel (alkane or alkene) and you need oxygen (O2) and you need energy in the form of heat
Why does fire need air?
Fire needs the oxygen in the air. Any other source of oxygen would also sustain fire.
What does a fire need to burn well?
oxygen
Does putting out fire need oxygen?
No. Adding oxygen to a fire will make it burn faster and hotter. In fact, one of the ways of putting out a fire is to cut off the supply of oxygen.
What are the 3 ingredients of fire?
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.
What do you need to start a fire?
To start a fire, you will need fuel (such as wood or paper), a spark (from matches, a lighter, or a fire starter), and oxygen. It's important to have a safe and controlled environment to prevent the fire from spreading uncontrollably.
Can a fire burn in a room with no oxygen?
No it can't. You need oxygen to burn for it to work.
Does fire need oxygen in order to burn?
yes it does
What ingredients do you need for a fire?
Fuel, oxygen and heat.
Does fire need oxygen to keep burning?
Yes.
What type of gas does fire need?
Oxygen is required in order for a fire to continue burning. Without oxygen a flame will extinquish itself.
Do you need air to have a fire?
Yes you need air. Or more correctly oxygen.
What gas in the air do you need to make fire?
Oxygen is the gas needed to make fire. It supports the combustion process by reacting with the fuel to produce heat and light.
