Dry wood, fire, ect, oxygen, and a spark are things that are needed for fire to burn.
The three things needed to make a fire burn, what is called the Fire Triangle, are 1] oxygen 2] heat 3] fuel
for wood to burn you need fire
it can burn things
it can burn things
There are three things needed for fire. Fuel (gasoline), a spark and oxygen. So your answer is oxygen.
it can burn u !
For something to burn, three key elements are required: fuel, heat, and oxygen. The fuel is what will undergo combustion, the heat is necessary to initiate the combustion reaction, and oxygen is needed for the fuel to react and sustain the burning process.
depends what it is but for most things yes
Actually you need three things. Fuel-something that will burn, oxygen and heat. If you take any of the three things away the fire will die out.
simple. fire comes, fire burn down trees and burrows and stuff, fire burn up animals, and the forest is left dead.
You shouldn't burn fallen leaves because they can set other flammable things on fire, causing a deadly fire.
In general, no, it accelerates / increases fires. If the fire is based on methane, say, and the oxygen displaces all the methane, then the fire will go out. If the oxygen is passed through / across the fire at something approaching supersonic speed, if the fire doesn't go out, it *will* go somewhere else.
