Why does the increased level of nutrients in the water affect the survival of aquatic organisms?

Solution
- Addition of nutrients in water flourishes the growth of microorganisms like algae which uses up the dissolved oxygen from the water.
- When algae die, they become food for decomposers such as bacteria; they also use the dissolved oxygen, thus reducing oxygen content even further. Their thick growth also stops sunlight from reaching the water.
