100
A place where elements are stored
What is a reservoir?
100
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?
what is in animals an plants
200
causes nitrogen fixation
What are lightning, bacteria, and cyanobacteria
200
stored in soil
What is ammonia
200
Are removing nitrogen from the atmosphere faster than it can be replaced
What are humans
300
The major abiotic reservoir for nitrogen.
What is the atmosphere?
300
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?
