Nitrogen cycling

Part of nutrient cycling (The movement of nutrients from environment into plants and again back to the environment)

Types of Nutrient cycling

1.Gaseous cycle(if it's reservoir is gas ie nitrogen)

2. Sedimentary cycle

Process of nitrogen cycle

1.Nitrogen Fixation

2.Ammonification

3.Nitrification

After nitrification some nitrates are taken by the plants,while others again went to the atmosphere.

Types of nitrogen fixation bacteria

1.Symbiotic bacteria( ie Rhizobium,Frankia,Azospirillium)

2. Free living bacteria( ie cyanobacteria,Nostoc,Azotobacter,Anabaena etc)

Nitrification.

Bacteria that convert Ammonia into nitrites

1.Nitrosomonas.

2.Nitrococcus.

Bacteria that convert nitrites into nitrates

1.Nitrobacter.

Bacteria that convert waste( ie from food chain) to ammonia include

1.Bacillus.

2.proteus.

3.clostridium.

Bacteria that undergoes denitrification Include pseudomonas.

Through these ways the process of nitrogen cycle takes place.
