Question

Nitrogen fixation can be done by:

• A. Industries
• B. Rhizobium
• C. Lightening
• D. All of the above

Answer 1

The correct option is D

All of the above

The correct option is D.

Explanation of the correct option:

1. The conversion of atmospheric nitrogen into nitrates and nitrites, which are then utilized by plants and animals, is a process known as nitrogen fixation.
2. There are techniques for fixing nitrogen, including industrial operations and lightning.
3. Because it is needed in the production of proteins, nitrogen is crucial for the existence of life.
4. Rhizobium, industrial processes, and lightning are all capable of nitrogen fixation.
5. A commercial procedure called the Haber's process is used to fix nitrogen.
6. Ammonia is created during this process by converting nitrogen.
7. Water, natural gas, which provides hydrogen, and iron, which serves as the catalyst are the basic ingredients needed for catalysis. Air provides nitrogen.
8. Rhizobium can also fix nitrogen. They transform it into inorganic nitrogen. After that, it is converted into amino acids, which plants use.
9. Lightning can fixate nitrogen as well. In this process, the atmosphere's nitrogen and oxygen combine to generate oxides of nitrogen.
10. These gases create weak nitric acid when they interact with rainwater. The soil mineral reacts with these traces of nitric acid to create nitrates.

Final answer: Nitrogen fixation can be done by industries, Rhizobium, and lightning.
