Dentrification |
NO3 (nitrate) becomes N2 (gas) and goes into atmosphere |
|
Nitrification |
NO2 (nitrate) becomes NO3 (nitrate), usable by plants |
|
Nitrogen Fixation |
N2 (gas) becomes NO2 (nitrate) and can be taken in by plants |
|
Legumes |
plant organisms involved in getting nitrogen gas into NO3 (have root modules with bacteria that do the job) |
|
Nitrogen-Fixing Bacteria |
Organisms in a mutual relationship with the plants above in getting nitrogen into a usable form |
|
Bacteria |
kind of organisms in the soil involved in every step of the nitrogen cycle, named after their particular task |
|
Decomposer |
major niche of organisms that are involved in every step of the nitrogen cycle |
|
Ammonia |
(NH3) Waste product of animals during respiration, released during excretion. It is usually found as a liquid, but it can volatilize into a gas. |
|
Organic Nitrogen |
(CaHbNcOd) Organic molecules containing nitrogen come in many forms from amino acids to proteins to lipids. |
|
Nitrate |
(NO3) found as a liquid and is very easily washed out of the soil and into groundwater or streams. |
