a. increased plant growth leading to a decrease in fish populations
Fertilizer runoff can cause an increase in nutrient levels in aquatic ecosystems, particularly nitrogen and phosphorus. This often leads to eutrophication, which is characterized by excessive growth of algae (algal blooms). While this initial increase in plant growth may seem beneficial, it can lead to oxygen depletion in the water when the algae die and decompose, resulting in decreased oxygen levels. This lack of oxygen can harm fish populations and other aquatic life, ultimately leading to a decrease in fish populations.
