Denitrification Flashcards
0
Q
Occurs in
A
Water-saturated soil and aquatic environments.
1
Q
Denitrification converts
A
Fixed nitrogen back to dinitrogen (and to N2O and NO)
2
Q
Occurs in oxygen-poor environments,
A
Nitrate is added by diffusion.
3
Q
The production of nitrus oxides, N2O,
A
Significantly contributes to the GH effect.
4
Q
Organic matter + NO3 ➡️
A
➡️ N2 / N2O / NO
Denitrification
5
Q
Denitrification is carried out by
A
Microbes in anaerobic conditions.
6
Q
Nitrate acts as an oxidising agent, the result is
A
Loss of nitrogen, converted to nitrus oxide, N2O, and nitrogen gas, N2.
7
Q
Denitrifying bacteria use
A
NO3- instead of O2
