Nitrogen cycle is important to humans because it converts nitrogen into a form that humans can obtain by eating other organisms.

NITROGEN CYCLE:

  • Nitrogen cycle involves the manner by which nitrogen is recycled in the environment i.e. from the soil to the atmosphere and vice versa.

  • Nitrogen is fixed by bacteria present in the root nodules of leguminous plants. The plants absorb nitrogen in form of nitrates.

  • Human beings benefit from this process when they feed on organisms like plants that have converted nitrogen to a usable form.

  • Therefore, nitrogen cycle is important to humans because it converts nitrogen into a form that humans can obtain by eating other organisms.
