Which characteristic is typical of eutrophic lakes during the summer?

Eutrophic lakes are characterized by high levels of nutrients, especially nitrogen and phosphorus, which promote excessive growth of algae and aquatic vegetation. During the summer months, these lakes experience a boom in aquatic plant growth due to increased sunlight and warm temperatures, leading to a proliferation of algal blooms and aquatic weeds. This can result in reduced water clarity and may create a dense layer of vegetation that can affect the overall health of the aquatic ecosystem.

The increase in plant biomass can lead to further consequences, such as oxygen depletion when the plants die and decompose. As a result, while aquatic weeds are flourishing in eutrophic lakes during the summer, there is often a competition for resources among species, affecting the balance within the ecosystem. This characteristic makes option B the most accurate description of eutrophic lakes in summer.
