A stream that runs through a farm field is experiencing dangerously low dissolved oxygen levels. About 1 week before the oxygen levels dropped the farmer plowed and fertilized the field. A day later heavy rains washed soil and fertilizer into the stream. Several days after the rains, the water was green and cloudy, now the water has cleared and the dissolved oxygen levels have dropped to dangerous levels. Write a paragraph explaining what is happening to the stream (use appropriate vocabulary). Give 2 examples of pollutants affecting the stream. Explain what action could be taken to mitigate the affects of the agricultural activities on the stream.
