Answer 2

Once bacteria have fixed nitrogen, it can be taken up by plants and animals, where it is used in the production of C. Proteins.

• Nitrogen is a macronutrient that is required by plants in large quantities. But, plants cannot directly utilize atmospheric nitrogen. So, there is a need to fix atmospheric nitrogen in which nitrogen is converted into ammonia.
• The plants absorb this ammonia and use it in the production of proteins. Proteins play structural and functional roles in plants. It is essential for photosynthesis, enzymatic reactions, growth of plants etc.
