Farmers often fertilize their crops for better yields.

The possible effect of fertilization on a watershed is that aquatic plants might grow at an accelerated rate causing the surface water to diminish. Here's why:

1. Fertilizers are rich in nutrients like nitrogen and phosphorus. When these nutrients are washed off the fields by rain or irrigation, they can end up in bodies of water such as rivers, lakes, or watersheds.

2. These nutrients can cause a rapid increase in the growth of aquatic plants and algae, a process known as eutrophication.

3. As these plants grow and spread, they can cover the surface of the water, blocking sunlight from reaching other plants and aquatic life beneath the surface.

4. This can lead to a decrease in the amount of oxygen in the water, which can harm fish and other aquatic organisms.

5. The rapid growth of these plants can also lead to a decrease in the amount of surface water, as the plants use up the water for growth.

So, the correct answer is C: Aquatic plants might grow at an accelerated rate causing the surface water to diminish.
