Explain how runoff from farms and golf courses can affect organisms in nearbly streams?

Runoff from farms and Golf courses often contains fertilizers, pesticides, and herbicides, which can lead to nutrient loading and chemical contamination in nearby streams. Excess nutrients, particularly nitrogen and phosphorus, can cause algal blooms that deplete oxygen levels in the water, harming aquatic organisms and disrupting ecosystems. Additionally, harmful chemicals can be toxic to fish and other wildlife, leading to decreased biodiversity and altered food webs. Overall, this runoff poses significant risks to the health of stream ecosystems and their inhabitants.
