A2 Biology (OCR)- The Nitrogen Cycle

Just made a diagram (it's not completely clear, sorry, I didn't realise the writing would be so small :S) and a powerpoint explaining the different areas of the nitrogen cycle in all the depth you'll need to know for your A2 exam. :)

There are some scientific errors within this powerpoint:

  • Nitrogen gas is fixed into ammonium ions or NITRATE ions (NO3-)
  • In denitrification, nitrate ions are converted back into NITROGEN gas (not oxygen), and nitrous oxide
