Why does the level of oxygen stay constant?
If you're talking about the level in the air, which I assume you are, it's because as we exhale, the oxygen we inhaled is replaced with carbon dioxide, which trees "breathe" in. Trees, or any plant, then releases oxygen after it completes photosynthesis with the carbon dioxide.
How much oxygen in air?
Oxygen makes up about 21% of Earth's atmosphere. This percentage remains relatively constant at different altitudes within the troposphere, where most of Earth's weather occurs.
Is there more oxygen on the floor?
Generally, oxygen levels remain constant in a room regardless of height. However, due to air circulation, oxygen may be slightly better at floor level in areas with good ventilation. It is always advised to prioritize regular ventilation and fresh air circulation in enclosed spaces for optimal oxygen levels.
What happens to oxygen level at high altitudes?
At high altitudes, the oxygen level in the air decreases because the air is less dense due to lower atmospheric pressure. This reduced oxygen level can lead to symptoms of altitude sickness like fatigue, dizziness, and shortness of breath in individuals not acclimated to the altitude.
Why does the oxygen in air not finish?
The oxygen in the air does not "finish" because it is continuously replenished through processes like photosynthesis, where plants produce oxygen, and atmospheric circulation that redistributes it around the Earth. Therefore, the balance between oxygen production and consumption ensures that there is a constant supply of oxygen in the air.
What is the concentration of oxygen in inhaled air?
Exhaled air contains 16% oxygen and 21% when inhaled.
Which atmospheric gases do photosynthesis and cellular respiration help keep constant?
Photosynthesis helps keep oxygen levels constant by converting carbon dioxide into oxygen, while cellular respiration helps keep carbon dioxide levels constant by converting oxygen into carbon dioxide. These processes are vital for maintaining the balance of atmospheric gases essential for life on Earth.

How much air is the the oxygen is in the morning?
Concentration of oxygen in dry air is 20,946 %.
What level inhaled oxygen?
21% of the air we inhale is oxygen
What is the average oxygen level in air at sea level?
21%
Is there more oxygen on the floor?
Generally, oxygen levels remain constant in a room regardless of height. However, due to air circulation, oxygen may be slightly better at floor level in areas with good ventilation. It is always advised to prioritize regular ventilation and fresh air circulation in enclosed spaces for optimal oxygen levels.
Can whales keep oxygen in their bellies?
Whales keep air, and thus oxygen, in their lungs, not in their bellies
How much oxygen have you got in the air?
The Earth's atmosphere is composed of roughly 21% oxygen. This level of oxygen in the air is ideal for human respiratory needs.
What's the percentage of oxygen in air at sea level to 4 decimal places?
2.66666666667 is the decimal of oxygen in the air
Why does our heart rate increases when we are high above sea level?
The air becomes thinner so less oxygen in every heart beat so to keep up the oxygen it has to beat faster
