Nitrogen Cycle- Morenike Dosu
Storyboard Text
- Hi! Im Sammy and today we'll be talking about the Nitrogen Cycle! You'll be meeting some of my friends as we talking about the cycle.
- Did you know, Nitrogen takes up 78% of the atmosphere?
- Hi im Luna! The first step to the Nitrogen Cycle is called Nitrogen Fixation.
- Nitrogen fixation is the process by which nitrogen is taken from its molecular form (N2) in the atmosphere and converted into nitrogen compounds useful for other biochemical processes.
- Atmosphere
- N

- Im Charlie! Our next stage is Nitrification
- This is the process by which ammonium gets changed into nitrates by bacteria. Nitrates are what the plants can then absorb
- Assimilation is the process by which plants and animals incorporate the NO3- and ammonia formed through nitrogen fixation and nitrification.
- Whats Up! Im molly, the next part of the cycle is called Assimilation.
- Plants take up these forms of nitrogen through their roots, and incorporate them into plant proteins and nucleic acids.
- N
- N
- During ammonification, the plant or animal that you are a part of dies. They are left to be converted back into ammonium by decomposers (bacteria and fungi that break down dead organisms).
- N
- Lastly Denitrification is the process that converts nitrate to nitrogen gas, thus removing bioavailable nitrogen and returning it to the atmosphere.
- Thats the end! Hoped you enjoyed learning about the steps of the Nitrogen cycle. :D
