Answer:
Hello. You did not enter the options, but the organisms use nitrogen in the following ways:
- Production of amino acids.
- Protein production.
- Production of DNA and RNA nucleic acids.
- Plant growth.
Step-by-step explanation:
Nitrogen is an essential chemical element for the existence of life on Earth, since it is a component of all the amino acids in our body, components of the nitrogenous bases that make up the DNA and RNA molecules, a component of proteins, in addition to allowing the growth of vegetables that will serve as food for other living beings. Approximately 78% of the air we breathe is composed of nitrogen from the atmosphere (N2), which is its largest reservoir.
Despite this, few living beings have the ability to absorb it in its molecular form (N2). It turns out that nitrogen, like iron and sulfur, participates in a natural cycle during which its chemical structure undergoes transformations in each of the stages, serving as a basis for other reactions and thus becoming available to other organisms - this being great importance of the nitrogen cycle (or "nitrogen cycle").
