Question

Why is bacteria an essential part of the nitrogen cycle?

Answer 1

The nitrogen cycle moves nitrogen back and forth between the atmosphere and organisms.

Bacteria change nitrogen gas from the atmosphere to nitrogen compounds that plants can absorb.

Other bacteria change nitrogen compounds back to nitrogen gas, which re-enters the atmosphere.

Answer 2

Hi dude.....

HERE IS UR ANSWER:

• The nitrogen gas must be changed to a form called nitrates, which plants can absorb through their roots. The process of changing nitrogen gas to nitrates is called nitrogen fixation. It is carried out by nitrogen-fixing bacteria.
• Nitrifying bacteria change the ammonium ions into nitrites and nitrates (RHIZOBIUM)

HOPE THIS HELPS....
