Nitrogen Cycles through Ecosystems

Nitrogen cycles through ecosystems
  • Nitrogen is required for all life.
  • Almost 78% of the air is nitrogen, but organisms cannot use nitrogen in gaseous form.
  • In the nitrogen cycle, bacteria in soil and roots fix nitrogen by changing it from a gas to nitrate compounds that can be taken up by plants.
