Which of the following is an example of human-induced nitrogen fixatio...
Human-induced nitrogen fixation occurs through nitrogen fixation by nitrogen-fixing bacteria (Option C). While there are natural processes like lightning and nitrogen fixation by leguminous plants, human activities such as the use of synthetic fertilizers and industrial processes have significantly increased the contribution of nitrogen-fixing bacteria in fixing nitrogen for agricultural purposes.

Human-induced nitrogen fixation:
Nitrogen fixation is the process by which atmospheric nitrogen is converted into a form that plants can use for growth. While natural sources of nitrogen fixation include lightning and nitrogen-fixing bacteria, human activities also play a significant role in this process.
Nitrogen fixation by nitrogen-fixing bacteria:
One of the most common examples of human-induced nitrogen fixation is the use of nitrogen-fixing bacteria in agriculture. Farmers often add nitrogen-fixing bacteria to the soil to increase nitrogen availability for crops. These bacteria form symbiotic relationships with leguminous plants, such as peas and beans, and help convert atmospheric nitrogen into a form that the plants can use.
Impact of human-induced nitrogen fixation:
- Human-induced nitrogen fixation has significantly increased the amount of nitrogen available for plant growth, leading to higher crop yields.
- However, excessive use of nitrogen-fixing bacteria and other nitrogen fertilizers can also have negative impacts on the environment, such as pollution of water bodies and soil degradation.
In conclusion, nitrogen fixation by nitrogen-fixing bacteria in agriculture is an example of human-induced nitrogen fixation. This practice has both positive and negative impacts on the environment, highlighting the importance of sustainable agricultural practices.
