- yes do you know that nitrogen takes 78% of the earth's atmosphere
- do you know that nitrogen has a big part in our food?
- Yes there is a cycle . It is called Nitrogen cycle.I'll show you the steps
- hmm.... what do you mean by that? like is there a cycle?
- the first step in nitrogen cycle is Nitrogen fixation. this step helps nitrogen viable to plants after that nitrogen then turns to ammonia when it breaks down to the sooil
- NITROGEN
- Nitrogen takes up to 78% of the atmosphere
- N

- Next step is nitrification,here the bacteria in the soil turns to ammonia then into nitrates. The plants absorbs this bacteria.This bacteria is important because it helps nitrogen change during the stages
- N
- N
- N
- SOIL
- N
- The next step are assimilation and ammoficationin assimilation .In this stage plants get nitrogen to absorb the nitrates and it is used for amino acids and nucleic acids
- In ammofication the decomposers like bacteria they turn into nitrogen then ammonia si it can be in the cycle again
- And finally the last step is the denitrification in this step here we will see the excess nitrogen from the soil will return to the earth’s atmosphere
- soil
- N

- the end :)
- In ammonification this is where the plant dies or animal dies.in this stage decomposers turn into nitrogen then ammonia
- The next steps are assimilation and ammonification. assimilation this is where the plants really get nitrogen and absorbs the nitrates
- And the last step this is the Dentrification.In this step the excess nitrogen that is in the soil it will go back amd flow in the atmospherethe end.
