Fire itself doesn't "use" energy in the way a living thing does. Instead, it's a chemical reaction that releases energi. Här är uppdelningen:

* kemisk reaktion: Fire is a rapid chemical reaction called combustion. In this reaction, a fuel (like wood or gas) combines with oxygen.

* Energiutsläpp: This reaction releases energy in the form of heat and light. This is why fire feels hot and we see flames.

* Fuel Source: The fuel provides the chemical potential energy that gets released during the combustion.

So, to be precise, fire doesn't "use" energy. It's the process of releasing chemical potential energy stored within the fuel, transforming it into heat and light.
