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 is the main reason humans need nitrogen to survive to?
nitrogen is used to help the body eliminate wastes.
Which gas do human being need to survive?
human beings need nitrogen for building proteins and o2
Why is Mercury unfit for human life?
Because it is to close to the sun, and lack of nitrogen and oxygen which we need to survive.
Is the air we breathe in all nitrogen?
No. If it were, we would die within minutes. If we ignore the variable amount of water vapor, air is 78% nitrogen and 21% oxygen. We need that oxygen in order to survive.
Why do farmers not need to apply carbon to grow their crops but often need to add fertilizer containing nitrogen and phosphorus?
There is ample carbon in the carbon dioxide in the air for plants to survive.
What does a pea plant need in order to survive?
Pea plants need sunlight, water and nitrogen rich fertilizer to survive.
What is the main reason humans need nitrogen to survive to?
nitrogen is used to help the body eliminate wastes.
Which gas do human need to survive?
human beings need nitrogen for building proteins and o2
Which gas do human being need to survive?

What major elements do you need to survive?
Oxygen Carbon Hydrogen Nitrogen Phosphorus Sulfur
What 4 big molecules do all organisms need to survive?
Carbon Oxygen Hydrogen Nitrogen
Why is Mercury unfit for human life?
Because it is to close to the sun, and lack of nitrogen and oxygen which we need to survive.
Do you need nitrogen to survive?
Humans do not need nitrogen gas to live, but the nitrogen atom is essential in the DNA molecule that stores human, and other animal and plant, genetic information.
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.
