The nitrogen cycle is an example of a cycle. Its processes include the conversion of atmospheric nitrogen into ammonia, which is called Choose... . Nitrogen is returned to the atmosphere in the process of Choose...

nitrogen fixation; denitrification

Explanation:

In a typical nitrogen cycle, the nitrogen in the atmosphere is converted into ammonia in a process known as nitrogen fixation. The ammonia is then converted into a usable form (nitrate or nitrite) for plants and other living organisms in a process known as nitrification. Nitrogen is returned to the atmosphere in a process known as denitrification.

Hence, the correct words to fill the gaps would be nitrogen fixation and denitrification.
