It converts nitrogen into a form that humans can obtain by absorbing it through their skin.

Detailed explanation-1: -It converts nitrogen into a form that humans can obtain by absorbing it through their skin. See nitrogen cycle is important to human because nitrogen is an important component of proteins and nucleic acids that are the building blocks of genetic material.
Detailed explanation-2: -The nitrogen cycle matters because nitrogen is an essential nutrient for sustaining life on Earth. Nitrogen is a core component of amino acids, which are the building blocks of proteins, and of nucleic acids, which are the building blocks of genetic material (RNA and DNA).
Detailed explanation-3: -Nitrogen is abundant in the environment but humans can’t use it directly from air or soil. So, humans depend upon green plants and microbes to convert them into a usable form for using them. Nitrogen is an important component and is used to make amino acids, which in turn is used to make proteins.
Detailed explanation-4: -Human can’t utilise nitrogen through respiration, but can absorb through the consumption of plants or animals that have consumed nitrogen rich vegetation. The air we breathe is around 78% nitrogen, so it is obvious that it enters our body with every breath.
