1. How can the presence of coal-fired electricity plants affect the ability of lakes to support life?
2. Suppose there has been a sudden growth of algae in a lake in cottage country.
(a) Suggest three possible causes for this situation.
(b) Explain what could happen in the lake.
Answer (2)
Coal-fired electricity plants can affect lakes by **causing **water pollution , excessive growth of algae, and changes in oxygen levels and pH balance. ;
Coal-fired electricity plants can harm lakes by causing pollution that leads to algal blooms, which deplete oxygen and disrupt aquatic ecosystems. Sudden algae growth can be caused by nutrient runoff, warm temperatures, or stagnant waters, and can result in diminished light and oxygen levels in the lake. These changes threaten fish and overall biodiversity in these environments.
