Around 16% of oxygen in the atmosphere is needed for burning to occur. This is the minimum concentration required for most combustion reactions to sustain.
The minimum amount of oxygen needed to sustain a fire in the atmosphere is about 16% oxygen. Below this level, the fire would not have enough oxygen to continue burning.
Oxygen must be at least 16% of the atmosphere to sustain the burning process. Below this level, fires may not be able to burn efficiently or sustain themselves.
The oxygen needed for burning wood comes from the surrounding air. During the combustion process, oxygen molecules from the air react with the wood to produce heat, light, and various byproducts like carbon dioxide and water vapor.
Historically, the percentage of oxygen in the atmosphere has fluctuated due to natural factors such as volcanic activity, changes in plant and algae populations, and variations in Earth's climate. Human activities, such as deforestation and the burning of fossil fuels, have also contributed to changes in the oxygen levels, although these changes are not significant enough to have a noticeable impact on the overall composition of the atmosphere at this time.
The atmosphere is composed of approximately 21% oxygen.

The percentage of oxygen in the Earth's atmosphere by mass is approximately 21.
At a minimum, oxygen must be what percentage of the atmosphere to sustain the burning process?
Oxygen.
Oxygen is the gas needed for burning in the fire triangle. Without oxygen, combustion cannot occur.
About 21% of the Earth's atmosphere is composed of oxygen.
About 21 of the Earth's atmosphere is made up of oxygen.
