How is the nitrogen cycle important to humans?

Question

It produces free nitrogen that can remove carbon dioxide from the atmosphere.
It converts nitrogen into a form that humans can obtain by eating other organisms.
It produces nitrogen compounds that humans can breathe.
It converts nitrogen into a form that humans can obtain by absorbing it through their skin.

Answer 1

The correct statement about the importance of the nitrogen cycle to humans is:

It converts nitrogen into a form that humans can obtain by eating other organisms.

The nitrogen cycle involves various processes that convert atmospheric nitrogen (N₂) into usable forms, such as ammonia (NH₃) and nitrates (NO₃⁻), which are utilized by plants. Humans and other animals obtain nitrogen by consuming these plants or other organisms that have assimilated nitrogen. Nitrogen is crucial for the synthesis of amino acids, proteins, and nucleic acids, which are essential for life.
