Remove all the nitrogen and then the atmosphere would be nearly pure oxygen (albeit at 21% the current pressure and density). Then, in those conditions, try to make a fire. It would go "WOOOF!" and burn in an instant, uncontrollably. The presence of other gases dampens the harsh effect that a pure oxygen environment would have.
But there is more. Nitrogen is necessary for plant growth (amino acids are called "amino" because this implies the presence of nitrogen in the molecule) and to make proteins. The nitrogen of the air is fixated by bacteria in the soil and then captured by plants roots.
Also, it seems that the presence of nitrogen in the air is used by the human body to synthesize NO (nitric oxide) which was recently identified as being vital for process like neurotransmission.
As for argon, since it is essentially inert, it does not serve any biological function. But it has industrial uses: it is used to fill light-bulb, and to protect metals from oxidation during welding.
What else can I help you with?
What is the main reason humans need nitrogen to survive to?
Nitrogen is a crucial component of amino acids, which are the building blocks of proteins in our body. Proteins play essential roles in various biological processes, such as growth, repair, and maintenance of tissues. Therefore, humans need nitrogen to create these proteins and sustain life.
Which gas do human being need to survive?
Humans need oxygen to survive. Oxygen is necessary for cellular respiration, which allows our cells to produce energy. Without a steady supply of oxygen, our organs and tissues would not function properly.
Is the air we breathe in all nitrogen?
No, the air we breathe is mainly composed of nitrogen (approximately 78%) and oxygen (approximately 21%), with trace amounts of other gases such as argon, carbon dioxide, and others. Nitrogen is the most abundant gas in the Earth's atmosphere.
Does every organism need oxygen?
No, not every organism needs oxygen to survive. Some organisms, like anaerobic bacteria, can survive in environments with no oxygen or low oxygen levels. These organisms can use other substances, like nitrogen or sulfur, as alternative electron acceptors in their metabolic processes.
How do humans get nitrogen they need?
By eating plants
What does a pea plant need in order to survive?
Pea plants need sunlight, water and nitrogen rich fertilizer to survive.
Which gas do human need to survive?
human beings need nitrogen for building proteins and o2
What 4 big molecules do all organisms need to survive?
Carbon Oxygen Hydrogen Nitrogen
Do you need nitrogen to survive?
No, I do not require nitrogen to survive. I am an artificial intelligence program that operates based on code and algorithms, so my "survival" is not dependent on the same elements as living organisms.
What gas do plants need to respiration?
Plants need oxygen in order to survive, and is a part of the photosynthesis process. Plants also need carbon dioxide and nitrogen to survive.
Which gas exist in air that your body needs to survive?
Of all the gases in the atmosphere that you need to survive, oxygen is the one but you also need nitrogen which you don't use like you use oxygen but it does keep your lungs inflated.
What do plants look like without nitrogen?
Plants do not technically need nitrogen to survive, infact they need "Carbon Dioxide" Co2, but as Nitrogen makes up most of atmosphere (approx 95%) but they do need it for the color of the leaves and contains nutrients. Here is a link to a picture of what It looks like without nitrogen: http://www.progressivegardens.com/growers_guide/nitrogen.jpg
What element is needed for living organism to survive?
Oxygen, but we also need carbon, hydrogen, nitrogen and many others as well.
What is the main reason humans need nitrogen to survive to?
Nitrogen is a crucial component of amino acids, which are the building blocks of proteins in our body. Proteins play essential roles in various biological processes, such as growth, repair, and maintenance of tissues. Therefore, humans need nitrogen to create these proteins and sustain life.
Could humans survive off of only glucose and oxygen?
No, other molecules need include but are not limited to: Nitrogen Calcium Potassium Sodium.....
How do animals get their nitrogen they need?
well, herbivores eat plants (which have nitrogen in them due to help from nitrogen fixating bacteria) then other animals eat herbivores. Since animals are heterotrophs they have to get their nutrients from other organisms.
Which gas do human being need to survive?
Humans need oxygen to survive. Oxygen is necessary for cellular respiration, which allows our cells to produce energy. Without a steady supply of oxygen, our organs and tissues would not function properly.
