Nitrogen makes up approximately 78% of the earth's atmosphere. Nitrogen is the primary building block of amino and nucleic acids, which are essential to life. The nitrogen in the atmosphere must undergo natural fixation to change form from gas to liquid. Then, through precipitation, the nitrogen is absorbed in the soil and becomes a crucial component of food production in plants, thus beginning the food chain.
