उत्तर
A sudden increase in the nitrogen and other soil compounds in the pond will lead to an increase in the population of algae and phytoplanktons (bloom of algae or bloom of phytoplanktons) as they nitrify very quickly and multiply. This will, eventually, alter the population of other organisms present in the pond.
