Question

Denitrification is the opposite of nitrogen fixation.

  1. True
  2. False

hintHint:

The process is the opposite of nitrogen fixation. Denitrification returns nitrogen gas back to the atmosphere, where it can continue the nitrogen cycle.

The correct answer is 'True'.


    • Denitrification is the opposite of nitrogen fixation.
    • Nitrogen fixation takes nitrogen gas out of the atmosphere and makes it biologically available, whereas denitrification converts that nitrogen back out of the soil back to nitrogen gas, completing the nitrogen cycle.
    • The denitrifying bacteria, convert some of the nitrates in the soil back into nitrogen gas in a process called denitrification
