Infer: How might a lake undergoing eutrophication affect a population of fish? TEKS 8.5B,8.5G,8.12B &sh population will increase because of extra nutrients. B) The fish population will decrease due to low oxygen and habitat loss. C) The fish population will not be affected. D) The size of the fish population will decrease, then increase rapidly.

Eutrophication is a process where a body of water becomes overly enriched with nutrients, leading to excessive growth of algae and other aquatic plants. This can result in a decrease in the oxygen levels in the water, as the decomposition of the dead algae and plants consumes oxygen. When oxygen levels are low, it can lead to the death of aquatic organisms, including fish, due to suffocation. Additionally, the excessive growth of algae can lead to habitat loss for the fish, as they may be smothered by the dense algal mats. Therefore, the most likely effect of eutrophication on a fish population is a decrease due to low oxygen levels and habitat loss.
