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.
