Amino Acids: These are organic molecules that combine to form proteins. They consist of an amine group, a carboxyl group, and a unique side chain.

Proteins: Large biomolecules consisting of one or more long chains of amino acids. They perform numerous functions within organisms including catalyzing metabolic reactions and DNA replication.

Nitrogen Cycle: The series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition.
