Question

Quizplus · Accepted Answer

Eutrophic lakes have high microbial and algal concentrations, leading to decreased oxygen levels and altered photosynthetic activities. However, the high nutrient levels in these lakes can also result in the growth of harmful algal blooms, which can harm or kill aquatic animals. Therefore, while some consumer aquatic animals may thrive in eutrophic lakes, others may be at risk.
