Nitrogen is essential for all living things because it is a major part of amino acids, which are the building blocks of proteins and of nucleic acids such as DNA, which transfers genetic information to subsequent generations of organisms. About 78 percent of the atmosphere is made of nitrogen, but plants and animals can't take nitrogen directly from the air. A process called the nitrogen cycle makes this happen.
