Reservoirs
Nitrogen Fixation
Nitrification
Denitrification
100
A place where elements are stored.
What is a reservoir?
100
The conversion of atmospheric nitrogen gas into forms useful to plants.
What is nitrogen fixation?
100
The biological oxidation of ammonia or ammonium to nitrite followed by the oxidation of the nitrite to nitrate.
What is nitrification?
100
The conversion of NH3 and NH4+ back into nitrate ions and then into nitrogen gas.
What is denitrification?
200
A biotic reservoir for nitrogen.
What are animals and plants?
200
These cause nitrogen fixation.
What are lightning, bacteria, and cyanobacteria?
200
This is stored in soil.
What is ammonia?
200
Created from fertilizer run off and decomposition
What are nitrates?
300
The major abiotic reservoir for nitrogen.
What is the atmosphere?
300
It creates ammonia to be used as a nutrient for plants.
What is bacteria?
300
Ammonia that is not taken up by plants may undergo this.
What is nitrification?
300
The soil that converts NH3 and NH4+ into nitrate ions.
What are the sediments of lakes and oceans?
400
This is lost to deep ocean sediments.
What is nitrogen?
400
They take up the ammonium converted from ammonia.
What are plants?
400
These convert detritus into simpler nitrogen containing inorganic compounds.
What are decomposers?
400
Created from burning fuel and using inorganic fertilizers.
What are nitrogen oxides?
