No, practically everything breaths oxygen besides non-living things
Yes the oxygen they breathe Is ALMOST dissolved in the water, so you can only breathe it with gills. Hop I answered your question. Thanks
No. It is only about 21% oxygen. Air is about 78% nitrogen.
Oxygen is what you breathe. only 20% of the air is oxygen. there ya go!
Because when you breath, you breath air which is 80% nitrogen and 20% oxygen. Also the air you breath out still has oxygen in it, you do not use all the oxygen and only produce a small amount of carbon dioxide in each breath.
Not that I know of. I only know that trees breathe in carbon dioxide an breathe out oxygen
What we breathe is air, and oxygen is just 20% of the air. Oxygen does not contain water, it is an element and it contains only itself. However, air does contain some water vapor.
It is not rues at all. Most of the gas inhaled is not oxygen it is nitrogen.
The air that we breathe in 78% nitrogen, 21% oxygen, and 1% carbon dioxide, water vapor, and other gases. We only need the oxygen though, so we breathe out the other gases with the carbon dioxide that our body produces during respiration. So to answer your question, it is nitrogen, but we breathe it in and then out- we don't use it. The only gas we use is oxygen to breathe.
I do not breathe at all since I am a computer program. My functions and responses are generated based on algorithms and programming.
Humans cannot breathe a combination of pure oxygen and hydrogen. Oxygen is necessary for respiration, but hydrogen is highly flammable and not suitable for breathing. Mixing the two gases is dangerous and can create a potential explosion hazard.
No, humans do not need to breathe nitrogen for survival. The air we breathe is mostly made up of oxygen, with only a small amount of nitrogen. Our bodies use the oxygen in the air for respiration, not the nitrogen.
Frogs can breathe underwater only for 20 minutes at a time. They breathe by using oxygen that is dissolved into the water and breathe through their skin.
