Historically, nitrogen was used to preserve food by displacing oxygen in containers to prevent spoilage. It was also used in the production of gunpowder and explosives. Additionally, nitrogen was crucial in the Haber-Bosch process for the production of ammonia, which revolutionized agriculture by allowing for the mass production of fertilizers.
Ammonia is a combination of nitrogen and hydrogen with one nitrogen atom and 3 hydrogen atoms. It can be used as a fertilizer, cleaner, refrigerant, an antimicrobial product for food products, and a couple of other uses.
The chemical name for the molecular formula NH3 is ammonia. Ammonia is composed of nitrogen (N) and three hydrogens (H). Ammonia has many uses in cleaning and as a solvent.
Nitrogen gas makes up the majority of the volume of the Earth's air: over 78%.
Urea is commonly used in fertilizers to provide a source of nitrogen for plants. It is also utilized in the production of cosmetics, lotions, and creams as a moisturizing agent. In addition, urea is used in certain medical tests to analyze kidney function.
Nitrogen and argon are both inert gases, but they have different properties and uses. Nitrogen is more abundant in the atmosphere and is commonly used in food packaging, as a coolant, and in the production of ammonia. Argon is heavier than air and is often used in welding, lighting, and as a protective gas in the production of metals.
The brain uses some as a neurotransmitter but there may be more reasons.
Nitrogen is used in the nitrogen cycle to help plants grow.

Everyone uses nitrogen. It is essential for life.
The Nitrogen that is used to make Ammonia (NH4) is extracted from the air.
Nitrogen is an essential part of proteins.
Plant growth.
the answer is suck off
Bacteria
Oxygen keeps animals alive, Nitrogen is not much use.
The nitrogen cycle uses bacteria to fix atmospheric nitrogen gas into a form that plants can use, a process known as nitrogen fixation. This bacteria, such as Rhizobium and Azotobacter, convert nitrogen gas into ammonia through biological processes.
