A eutrophic lake is characterized by an abundance of nutrients, particularly nitrogen and phosphorus, which promote the rapid growth of algae and aquatic plants. While these nutrient levels support a variety of life, they can lead to problems over time.
The statement about low turbidity conditions is false because eutrophic lakes typically experience high turbidity. This turbidity is caused by the excessive growth of algae, which can reduce water clarity. The high levels of nutrients in these lakes often lead to algal blooms, which can decompose and further reduce oxygen levels in the water.
In summary, eutrophic lakes are known for being nutrient-rich, can suffer from low oxygen levels due to decomposition processes, and are often turbid due to high algal concentrations. Therefore, the assertion that they have low turbidity is incorrect, making it the false statement among the options given.
