Nitrogen Cycle Flashcards
Learn the Key Processes
1
Q
Nitrogen Fixation
A
Bacteria in the soil and root nodules convert nitrogen gas into ammonium ions.
2
Q
Nitrification
A
The process of turning ammonium ions into nitrates and nitrates. This is done by groups of nitrifying bacteria.
3
Q
Assimilation
A
This is the uptake of nitrates from the soil by the roots of plants.
4
Q
Ammonification
A
In this process, decomposers turn nitrogen compounds from dead organisms and organic water into ammonium.
5
Q
Denitrification
A
The process of turning nitrate into nitrogen gas. This is done denitrifying bacteria.
