The nitrogen cycle reflects a more intimate side of energy needs, via its central role in the production of food. It is one of the places where the chemistry of the Earth and life come together, as plants extract nitrogen from their environment, including the air, to make food.
Nitrogen is a fairly common element in the Earth's crust. It is by far the most important element of the Earth's atmosphere, making up about 78.084 percent. The greatest use of nitrogen is in ammonia which is used for fertilizer production and to produce nitric acid. Nitrogen gas is used where an inert atmosphere (one without oxygen) is needed, such as in an ordinary light bulb. Nitrogen is also used to protect historic documents such as the Declaration of Independence.
