1. describe how farmers impact our water? use the words fertilizer, run - off, and contaminate in your answer.

Explanation:

Farmers use fertilizer on crops. When it rains, fertilizer can be carried by run - off (water flowing over the land) into water sources like rivers, lakes, or groundwater. This run - off with fertilizer contaminates the water, as the chemicals in the fertilizer (like excess nutrients) can disrupt aquatic ecosystems, cause algal blooms, and make the water unsafe for drinking or other uses if not properly managed.

Answer:

Farmers apply fertilizer to their crops to promote growth. However, during rainfall or irrigation, water can cause run - off, which carries the fertilizer from the fields into nearby water bodies (such as rivers, lakes, or groundwater). This run - off containing fertilizer contaminates the water. The fertilizer's nutrients (like nitrogen and phosphorus) can lead to problems like algal blooms, which deplete oxygen in the water and harm aquatic life, and can also make the water unfit for human consumption or other beneficial uses if the contamination levels are high.
