the nitrogen cycle

What is the bacteria that transforms Nitrogen N2 in the atmosphere to Nitrates NO3 in the soil?

Nitrogen fixing bacteria

How much % is Nitrogen N2 gas in the atmosphere?

78%

What is the Nitrogen N2 fixing bacteria called in clover nodules?

Rhizobium

What is the Nitrogen N2 fixing bacteria called in soil?

Azotobacter

What happens to Nitrates NO3 after they are taken from the atmosphere to soil?

They are absorbed by plants

How are Nitrates NO3 converted into Ammonia?

Bacteria of decomposition / Death Decay

What are the two types of Ammonia?

NH4 / NH3

What Nitrifying bacteria converts Ammonia into Nitrites NO2?

Nitrosomonas

What bacteria turns Nitrites NO2 into Nitrates NO3?

Nitrobacter

What does denitrification mean?

Denitrification is the process of which Nitrates NO3 get turned into Nitrogen N2 back again in the atmosphere through the action of Denitrifying bacteria.

Why is there two way the Nitrogen Cycle can go?

There is a chance that the Nitrates can be turned back into Nitrogen N2 by denitrification or it can get eaten/absorbed by plants/animals and then keep the cycle going.

Why do we need the nitrogen cycle?

The Nitrogen Cycle is the way nitrogen is recycled in nature.
