NItrogen Cycle

1. 1.Ammonification

1.1. release of ammonia

1.1.1. -protein from dead cells

1.1.2. -amino acids

1.1.3. -ammonia

2. 3.Denitrification

2.1. nitrate ion is reduce to molecular nitrogen gas

3. 2.Nitrification

3.1. ammonia oxidize to nitrate

3.1.1. -ammonia will undergo ionisation to form ammonium ion

3.1.2. -nitrite ion (nitrosomonas)

3.1.3. -nitrate ion (nitrobacter)

4. 4.Nitrogen Fixation

4.1. nitrogen gas converted into ammonia

4.1.1. - nitrogen fixing bacteria
