Nitrogen Cycle
Nitrogen: What is it?
•Nitrogen is essential to life on Earth. It is a component of all proteins and it can be found in all living systems.
•Nitrogen compounds are present in organic materials, foods, fertilizers, explosives and poisons. Nitrogen is crucial to life, but in excess it can also be harmful to the environment.
•Nitrogen is the fifth most abundant element in the universe. Nitrogen gas constitutes 78 percent of Earth's air.

Let's define the nitrogen cycle!
•The nitrogen cycle, in which atmospheric nitrogen is converted into different organic compounds, is one the most crucial natural processes to sustain living organisms.
•During the cycle, bacteria in the soil process or "fix" atmospheric nitrogen into ammonia, which plants need in order to grow.
•Other bacteria convert the ammonia into amino acids and proteins.

What happens if there is no nitrogen cycle?
1.Nitrogen acts as a diluent in the atmosphere. Pure oxygen would be too rich to breathe and make ignition and fires treacherous.
2.Nitrogen is the basic and essential building block of amino and nucleic acids. All the working in the human body is directly related to amino and nucleic acids.
3.Nitrogen is used as a fertilizer in soils, as an ingredient in industrial processes, and is released during the burning of fossil fuels.
Ammonia (NH3) is another nitrogen compound commonly used in fertilizers.
Nitric acid (HNO3) is a strong acid often used in the production of fertilizers.
4.Liquid nitrogen is used as a refrigerant for very low temperatures.
