No. Monoatimc oxygen is chemically unstable and is too reactive for people to breathe it safely.
Not that I know of. I only know that trees breathe in carbon dioxide an breathe out oxygen
We breathe because we are human beings. Also we need air to breathe and we need oxygen for our lungs. Did You Know? sugar is in our blood?
They respire the same way plants do, with oxygen molecules.
animals breathe oxygen, as you know, and exhale carbon dioxide. plants, trees for example, take in carbon dioxide and release oxygen. this is why there is plaenty of oxygen left for every living creature
i do not know if you mean a specie or place. but i do know that plants provides the earth with oxygen. if you are looking for a place, then look at a place with the most plants. if you are looking for a specie, plants, provide the earth withoxygen (plants breathe in carbon dioxide and breathe out oxygen)
i don't completely under stand your question, but if you're asking why the amount of it in the air doesn't change, the answer is simple. we breathe in oxygen and let out carbon dioxide. while plants "breathe in" carbon dioxide and let out oxygen. oxygen is also made from chemical reactions from the ocean. but this is not enough to supply this much life with oxygen, and we still don't know where all the extra oxygen came from.
Fish breathe oxygen, which they extract from the water with their gills.
DO YOU SERIOUSLY NOT KNOW THIS?!?!? It's because they need it to breathe in oxygen.
It is normally know as 'air' and air is made up mostly of nitrogen and oxygen. Oxygen is the gas that the body needs to survive.
it is important because if they don't know the temperature they
phospororus and oxygen are elements. to know they're atomic number and mass, check the periodic table. oxygen is the most abundant element on earth and is usually found as a gas. (you breathe oxygen.)
the air you breathe out is a mixture of oxygen, carbon dioxide sorry those are the only two that i definitely know i think there's a tiny bit of helium in there to
