Oxygen is replenished or released in nature when green plants make the use of Carbon Dioxide to perform photosynthesis
because of desanacanition
Animals remove oxygen from the atmosphere.
Mars' atmosphere contains 0.13% oxygen. Over 95% of the atmosphere on Mars is carbon dioxide.
No, because the atmosphere keeps in all the oxygen. Without the atmosphere the oxygen would escape.
Yes (higher= less oxygen, and vice-versa for lower.) actually the oxygen ratio remains the same but air gets less dense at altitude so you have to breathe a lot more air to get the oxygen you need
Oxygen
The source of oxygen in the atmosphere is a complicate stellar process.
It is constantly being replenished by plants, from the giant 100mtr trees to the tiny algae. These plants convert, by photo-synthesis, the carbon-dioxide breathed out by animals back into oxygen in the atmosphere.
Nitrogen is relatively inert and so will stay stable in the atmosphere. Oxygen on the other hand, is very reactive and is also in a constant cycle of being removed from the atmosphere by cellular respiration and replenished by photosynthesis. The higher concentration of oxygen in the atmosphere, the more likely it is to react with something, which will deplete the amount. Currently, the air is about 21% oxygen, but has reached levels as high as 35% during different periods.
Earth's atmosphere which is replenished by growing things.
Plants and other photosynthetic organisms in the process of making glucose (their food) from carbon dioxide and water (using light as the energy source) release the highly toxic waste product of this process called oxygen into the atmosphere.
Plants take in carbon dioxide then when they take that they give off oxygen
There is only about 2 years remaining. Starting next year, half of you will need to stop breathing every other day.just kidding. The atmosphere does not run out. It is replenished by green plants that make oxygen as part of photosynthesis. You may resume breathing now.
21% of the atmosphere is oxygen.
The atmosphere is 79.9% oxygen.
Oxygen debt is not a condition but rather a medical term that refers to the amount of oxygen that is lost during intense physical activity and needs to be replenished. This loss or debt of oxygen is replenished by heavy breathing that occurs during intense physical activity or when the physical activity ceases.
the environment which has the availability of oxygen it is called aerobic atmosphere and if the availability of oxygen is not there in atmosphere then it is anaerobic type We live in a aerobic atmosphere which has the oxygen available
No, there is no oxygen in Mercury's atmosphere because Mercury does not have an atmosphere.
