Nitrogen is important for all humans because it is a major part of amino acids, which are the building constituents of proteins and of nucleic acids such as deoxyribonucleic acid, which transfers genetic information to the next generation.
<h3>What is the nitrogen cycle?</h3>
It is the biogeochemical circuit that supplies nitrogen to living things and keeps it circulating in the biosphere.
Importance of the nitrogen :
- The nitrogen that is part of the atmosphere in the form of N₂ cannot be used by animals and plants, and for this reason, this mechanism is needed to convert the N₂ into usable forms.
- Following the order of the food chain, the nitrogen in the plants passes to the herbivorous animals and then to the carnivores, spreading between the different links of the food pyramid.
- Humans use nitrogen to make amino acids, proteins, nucleic acids, and DNA.
Therefore, we can conclude that the nitrogen is a vital circuit for the existence of Humans and all other living organism since we are unable to fix nitrogen from its gaseous form.
