Question

Which of the following biogeochemical cycles uses the reaction 2N2 + 6H2O --> 4NH3 + 3O2? (3 points) The phosphorus cycle The carbon cycle The water cycle The nitrogen cycle

Answer 1

The nitrogen cycle

Step-by-step explanation:

The nitrogen cycle is the process in which nitrogen (N₂) is converted to a biologically useful species (ammonia, NH₃).

We can also discard the other options given by the problem:

• There is no phosphorus nor carbon in the reaction.

• The water cycle involves water changing phases (tipically from gas to liquid to gas again), instead of reacting and producing oxygen.
