What are the 6 Steps in the Nitrogen Cycle? Using = NH3, Denitrification, No2 and NO3, Nitrification Bacterial nitrogen fixation, N2

Nitrogen fixation. Atmospheric nitrogen occurs primarily in an inert form (N2) that few organisms can use; therefore it must be converted to an organic – or fixed – form in a process called nitrogen fixation.

Nitrification.

Assimilation.

Ammonification.

Denitrification.

Explanation:

Does that help? :)

they are made of gases.

they have a spherical shape.

they make energy through fusion.
