There are many uses.
In liquid form it is very cold and is used for refrigeration.

Everyone uses nitrogen. It is essential for life.
By eating proteins as proteins have nitrogen in it
Do you mean manure? Manure has nitrogen that plants use.

Nitrogen is very important in fertilisers.
Most people use nitrogen to inflate jet plane tires.
During nitrogen fixation, nitrogen gas is converted into ammonia or other forms of usable nitrogen by nitrogen-fixing bacteria. This process is important because plants and other organisms cannot use atmospheric nitrogen directly in this form.
