When nitrate is reduced to dinitrogen gas (N₂),nitrogen is removed from the ecosystem and returned to the atmosphere through a series of reactions collectively known as

Question

Quizplus · Accepted Answer

The process described in the question is denitrification, which is the conversion of nitrate to dinitrogen gas and the subsequent release of nitrogen into the atmosphere. Choice A, nitrogen fixation, is the opposite process where nitrogen gas from the atmosphere is converted into a form usable by living organisms. Choice C, anammox reaction, is a process where ammonia is converted to dinitrogen gas without the intermediate production of nitrate, and is not mentioned in the question. Therefore, the best choice is B, denitrification.
