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...

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.

The nitrogen cycle processes include the conversion of atmospheric nitrogen into ammonia, which is called:

Nitrogen Fixation

Nitrogen is returned to the atmosphere in the process of:

Denitrification

Nitrogen is an important element that is used by organisms in their respective habitat. Nitrogen cycle is the process of changing ammonia from nitrogen through a process called nitrogen fixation.

Denitrification is the process of returning nitrogen back to the atmosphere after it has been converted to ammonia.

Therefore, the correct answer is nitrogen fixation and denitrification
