Humans primarily obtain the nitrogen they need for their bodies by consuming plants or other animals. Nitrogen is an essential element for the synthesis of amino acids, proteins, and nucleic acids. While nitrogen makes up a significant portion of the Earth's atmosphere, it is in the form of N2, which is not directly usable by humans. Instead, humans obtain nitrogen through the food chain, where plants assimilate nitrogen from the soil (in the form of nitrates and ammonium) and animals obtain nitrogen by consuming plants or other animals.
