No, in fact most early spacecraft the test animals, astronauts, or cosmonauts breathed pure oxygen. This was stopped after the Apollo-1 fire, which was attributed to defective wiring and a pure oxygen atmosphere. After that some nitrogen was added as a safety feature against fire.
No, humans do not need nitrogen to breathe for survival. The air we breathe is primarily made up of oxygen, with only a small amount of nitrogen.
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.
Animals get nitrogen from the proteins found in their food. When animals consume plants, they break down the proteins into amino acids, which are then used to build new proteins in their bodies. Nitrogen is an essential component of amino acids, which are the building blocks of proteins in animals.
nitrogen, oxygen
Animals need oxygen to breathe, and together with hydrogen, it makes water. Nitrogen is used by plants, and is one of the building blocks for proteins.
Air/gas animals and humans breathe in, and a little bit of nitrogen is included in the air it has just breathed in.
because of oxygen,nitrogen
because the haemoglobin present in our blood has no capacity to absorb nitrogen so the result is that the nitrogen is not absorbed and you breathe out the same amount of nitrogen as you breathed in.......
you breathe in more nitrogen then oxygen because there is 78% n in the air and 21% o in the air
When the animals breathe in nitrogen it goes into their bodies so when they die and decompose the nitrogen they breathed in is now in the soil and also when they fertilize on the land.
Nitrogen is required by plants and animals for protein synthesis
Plants and animals die and decomposers break down their nitrogen containing molecules to ammonia. All animals get the nitrogen they need by eating plants, by eating other animals that ate plants, or by eating animals that ate animals that ate plants.
