Correct Answer: C
Solution :
fertilizers such as nitrates, phosphates and urea used in agriculture to increase the crop yield are reach through irrigation, rainfall info river, ponds, lakes. Thus with the passage of these nutrients the water bodies become highly productive or eutrophic and this phenomenon is called eutrophication. With the addition of nutrients there is stimulated luxurient growth of algae in water. The blue-green algae form algal bloom and thus oxygen level is depleted (an oxygenic photosynthesis). Thus in a poorly oxygenated water with higher \[C{{O}_{2}}\] levels fish and other animals begin to die.
