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.

Is hot air richer in oxygen than damp air?
hot air is richer in oxygen than damp air because when you sex a girl it is hot
Does the space station have to fill up with air or oxygen?
It is filled with air, as prolonged exposure to pure oxygen is harmful to humans.
Is there any difference between air and space?
air (oxygen) does not exist in space. that's why astronauts have suits with oxygen tanks.
Is the air on moon breathable?
No, because people can only breathe with Earth air (which mainly consists of Nitrogen and Oxygen), and moon atmosphere has no Nitrogen or Oxygen.
Do they have oxygen in space?
No. There is no air in space. Our gravity holds in the atmosphere, including Oxygen and other gases.
How does the oxygen in the atmosphere get replenished?
Oxygen is replenished or released in nature when green plants make the use of Carbon Dioxide to perform photosynthesis
How is oxygen replenished in nature?
Plants take in carbon dioxide then when they take that they give off oxygen
How do the heart and lungs work?
When we breathe in our lungs fill with oxygen rich air. Membranes in the lungs exchange the oxygen from the air with carbon dioxide in the blood. Then we breathe out the spent air to inhale fresh. The blood, now replenished with oxygen, is pumped by the heart through the arteries to all cells in the body where the oxygen is exchanged with the cells for carbon dioxide and returned through the veins to the lungs.
Is oxygen debt a legitimate medical condition?
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.
Where do heterotrophs get oxygen from?
I had this on my BIO quiz earlier today. Because heterotrophs are not photosynthetic they receive their energy in the same way we do, food. Heterotrophs can be classified as consumers which means they eat (and get energy) from other plants or animals.
What does air supply for hummans?
Earth's atmosphere which is replenished by growing things.
Which planet is constantly being replenished by solar wind depositing oxygen and sodium atoms?
mercury
How many people needed oxygen?
From the air. The air consists of 78% nitrogen and 21% oxygen. The other 1% is made of argon, carbon dioxide and other gases. The oxygen is kept replenished when green plants photosynthesise. This involves the plant extracting the carbon dioxide from the air, absorbing water through its roots, and, using the green pigment chlorophyll in its leaves, convrts these two substances into sugars (its own food) and oxygen which is released into the air to replace what we have used.
Why is 80 percent of air nitrogen not oxygen?
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.
Facts about air?
Air is obviously necessary for human existence. When we breathe it in, our lungs capture the oxygen. When we exhale, we send out carbon dioxide. Carbon dioxide is then captured by plants, who send off a waste of oxygen once they're finished with it. Air is also matter. It really does have mass and volume. Air can also be found in more minor amounts in water. Fish circulate water through their gills, catching the oxygen but blowing the water back. Air is not found in outerspace. Plants are required to keep oxtgen returning to the planet since plants are the only way for oxygen to get replenished.
What happens to oxygen at the pulmonary capillaries?
The blood returning to the heart after delivering its load of oxygen is deoxygenated, but it is still carrying 75% of its full capacity. When this deoxygentated blood is pumped to the lungs and into the pulmonary capillaries, it meets oxygen rich air that has been inhaled. And, in tiny sacks called alveoli, the gas exchange occurs where carbon-dioxide is diffused into the air in the alveoli, and the oxygen is replenished back to 100% capacity so it can be pumped throughout the body tissues.
Is oxygen a air?
Oxygen is in the air.
