Oxygen is essential for supporting burning (combustion) and respiration in living organisms. Without oxygen, fires would not burn and animals and plants could not survive. Oxygen is crucial for the processes that keep us and other living things alive. An interesting fact is that oxygen makes up about 21% of the Earth's atmosphere, which is just enough to sustain life.

The main role of oxygen in the atmosphere is to support burning and respiration.
- Supporting Burning: Oxygen is essential for combustion, which is the process of burning. When a substance burns, it reacts with oxygen to produce heat and light. This process is crucial for various activities such as cooking, heating, and generating energy. Without oxygen, combustion cannot occur.
- Supporting Respiration: Oxygen is also vital for the process of respiration in living organisms. During respiration, organisms take in oxygen and use it to release energy from food. This energy is essential for the functioning of cells and the survival of organisms. Without oxygen, respiration cannot take place, leading to a lack of energy and ultimately, death.
In conclusion, oxygen plays a crucial role in the atmosphere by supporting burning and respiration, which are essential processes for life on Earth.
