Solution

Plot B in the given graph shows a sudden increase due to the presence of the chemical fertilizer.

The chemical fertilizer for a short period of time provides high nutrients to the crops.

These fertilizers are chemical inexpensive and promote the growth of crop yields.

After some times, the crop yield gets reduced because the negative toxic effect of the crops affects the soil fertility and the crop yield.
