Solution
The process of nitrogen fixation in the nitrogen cycle is best described as the conversion of nitrogen gas into ammonia by nitrogen-fixing bacteria.
Here's a step-by-step breakdown of the process:
-
Nitrogen Fixation: Special bacteria, known as nitrogen-fixing bacteria, convert nitrogen gas (N2) from the atmosphere into ammonia (NH3). This process is called nitrogen fixation.
-
Nitrification: The ammonia is then converted into nitrites (NO2-) by other bacteria. This is called nitrification.
-
Assimilation: Plants absorb these nitrites through their roots and convert them into nitrates (NO3-), which they can use to build proteins and other necessary compounds.
-
Denitrification: Finally, some bacteria in the soil convert nitrates back into nitrogen gas, which is released back into the atmosphere. This process is called denitrification.
So, the correct answer to your question is "Conversion of nitrogen gas into ammonia by nitrogen-fixing bacteria".
