Damage to the ecological structure and function of lakes because of deeper penetration of UV light into the water occurs because of a synergistic interaction among ozone depletion,acid deposition,and global warming.

UV light damages the ecological structure and function of lakes by harming the organisms living in them. Ozone depletion, acid deposition, and global warming all contribute to this problem in a synergistic manner, meaning their combined effects are stronger than their individual effects. This is because ozone depletion and acid deposition increase the amount of UV radiation that reaches the Earth's surface, while global warming can change the water temperature and nutrient levels in lakes, making them more susceptible to UV damage.
