Nitrogen Cycle

​First step of nitrogen Cycle

Step 1- Nitrogen Fixation- Special bacteria convert the nitrogen gas (N2 ) to ammonia (NH3) which the plants can use.

2 Step of nitrogen cycle

Step 2- Nitrification- Nitrification is the process which converts the ammonia into nitrite ions which the plants can take in as nutrients.

Third step of the Nitrogen Cycle

Step 3: Ammonification: Everything living eventually dies, and the nitrogen a particular organism was using when it croaked is taken to hand by bacteria that turn the nitrogen-rich corpse into ammonium, which can be picked back up by plants and used again.

Multiple Choice

What do you call the third step of Nitrogen Cycle

• Ammonification

• Nitrification

• Nitrogen Fixation

• Ammunition

Last step of Nitrogen Cycle

Denitrification is the process that converts nitrate to nitrogen gas, thus removing bioavailable nitrogen and returning it to the atmosphere.
