Answer:
The nitrogen cycle is important for humans, because in addition to being part of 78% of the atmosphere, it is indispensable for the growth of vegetables that are important for our food, in addition to being a necessary nutrient for some organic molecules essential to our organism, such as DNA, RNA and proteins.
Step-by-step explanation:
nitrogen nitrogen designates the process by which nitrogen circulates through soil and plants, based on the action of living organisms, which is essential for the maintenance of ecosystems. Nitrogen is a chemical element of great importance for life, used in the production of amino acids, nucleic acids and proteins.
Nitrogen is present in the atmosphere in the form of gas, this being its largest repository, since the atmosphere is composed of no less than 78% of this element. After the atmosphere, it is possible to find nitrogen in the oceans, in organic matter and also in the soil.
Despite being in the atmosphere, only a few algae and bacteria can consume it like this, integrating it with molecules. The nitrifying bacteria in the soil convert nitrogen and form nitrates, allowing this element to be absorbed by plants and animals, indirectly. Denitrifying bacteria return nitrogen to the atmosphere in gaseous form, closing the cycle.
