Question

Which two distinct microbial.Processes are responsible for.The release of fixed nitrogen as dinitrogen gas (n2 to the atmosphere?

Answer 1

Hey mate here's your answer

Anaerobic ammonium oxidation and denitrification

Solution:

Denitrification is a chemical process in which nitrates in the soil are reduced to molecular nitrogen (N.) which is released into the atmosphere. It is done by denitrifying bacteria like Pseudomonas denitrificans. Anaerobic oxidation of ammonium (NH4) also releases nitrogen in the atmosphere.
