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.
What else can I help you with?
What 2 processes are responsible for keeping the percentage of atmospheric oxygen at a constant level?
Photosynthesis by plants and algae, and respiration by animals and other organisms help maintain the percentage of atmospheric oxygen at a relatively constant level. Photosynthesis consumes carbon dioxide and produces oxygen, while respiration does the opposite.
How can you keep the oxygen level constant in the air?
Plants play a crucial role in maintaining the oxygen level in the air through the process of photosynthesis, where they absorb carbon dioxide and release oxygen. Additionally, reducing activities that contribute to air pollution can help in maintaining a stable oxygen level in the atmosphere. Regular monitoring and conservation of forests and green spaces also contribute to keeping oxygen levels constant.
Why does the nitrogen level in the atmosphere is higher than the oxygen level?
Because due to the over pollution and cutting down the tree's level of Oxygen is decreasing .The level of Nitrogen always remains constant in the atmosphere . The level of Nitrogen doesn't' depend on the level of the Oxygen level.
How much oxygen does the brain need to stay conscious?
The brain requires a constant supply of oxygen to function properly. As a general guideline, the brain needs about 20% of the body's total oxygen consumption to stay conscious. Any significant drop in oxygen levels can lead to impaired brain function or loss of consciousness.
Why is oxygen level remain constant?
Oxygen levels in the atmosphere remain relatively constant due to the balance between oxygen production through photosynthesis by plants and algae, and oxygen consumption through respiration by animals and microbes. Any significant shifts in this balance could affect oxygen levels and disrupt the delicate ecosystem that sustains life on Earth.
Why is it important for your blood pressure to stay at a constant level?
Keeping your blood pressure at a relatively constant level is likely to prevent strokes and other vascular accidents.

What is the concentration of oxygen in inhaled air?
Exhaled air contains 16% oxygen and 21% when inhaled.
Mass of oxygen in one breath changes as you climb from sea level?
The mass of oxygen in one breath remains constant as you climb from sea level. However, the decrease in atmospheric pressure at higher altitudes can make it feel like you are getting less oxygen with each breath, leading to symptoms of altitude sickness.
How do sea anemones get air?
Their tendrils wave in the water and "filter feed" the oxygen out of the water. This means they need constant motion to stay alive much like barnacles which latch onto whales and other ocean life to have this constant motion.
If balanced forces act on a person what does that mean about their motion?
It means they stay still, or they move at constant velocity.It means they stay still, or they move at constant velocity.It means they stay still, or they move at constant velocity.It means they stay still, or they move at constant velocity.
What is the partial pressure of oxygen on Mt Everest if the atmospheric pressure on Mt Everest is one-third the atmospheric pressure at sea level?
The partial pressure of oxygen on Mt Everest would be approximately one-third of the partial pressure of oxygen at sea level, assuming a constant composition of air. This decrease is due to the decrease in atmospheric pressure at higher elevations. This lower partial pressure of oxygen can lead to decreased oxygen availability for breathing at high altitudes.
What group of prokaryotes are organisms that require a constant supply of oxygen?
organisms that require a constant supply of oxygen from the prokaryotic group are called "obligate aerobes
