Our bodies consume oxygen through a process called cellular respiration.
Around 21% of the air you breathe is oxygen.
The air we breathe in contains more oxygen and less carbon dioxide compared to the air we breathe out. When we exhale, we release carbon dioxide and other waste gases that our body has produced through cellular respiration.
On average, humans breathe in about 21% oxygen from the air.
Oxygen makes up about 21% of the air we breathe.
The gas you breathe in from the air is called oxygen.
The air you breathe out contains less oxygen because your body extracts oxygen from the air when you breathe in and uses it during cellular respiration to produce energy. As a result, the air you breathe out has a higher concentration of carbon dioxide and less oxygen.
The air at the top of the mountain is less dense, meaning there are less particles of oxygen in a certain are than on the ground. It is harder to breathe because the air is so thin, there is not enough oxygen to breathe normally until you get used to it.
Because - the higher up the atmosphere you go - the less oxygen is in the air you breathe. Our bodies need a certain percentage of the air we breathe to be Oxygen - reduce the amount of oxygen in each breath, and it soon affects the body.
Oxygen is approximately 21% of the air we breathe.
Around 21% of the air you breathe is oxygen.
The air we breathe in contains more oxygen and less carbon dioxide compared to the air we breathe out. When we exhale, we release carbon dioxide and other waste gases that our body has produced through cellular respiration.
You blow out carbon dioxide, trees breathe it in, trees breathe out oxygen, you breathe in oxygen. It's the air cycle.
You blow out carbon dioxide, trees breathe it in, trees breathe out oxygen, you breathe in oxygen. It's the air cycle.
The oxygen content in the ocean is lower than the air humans breathe. The ocean contains less oxygen because it is not constantly replenished like the air on land, which is continuously refreshed by plants through photosynthesis.
On average, humans breathe in about 21% oxygen from the air.
