Your class is collecting macroinvertebrates (insects & other small animals found in water) to determine the pollution level in a local creek. Each macroinvertebrate that you collect has a 'Pollution Rating' between 0 and 10. A rating of 0 means the animal is usually found in very polluted water. A rating of 10 means it is only found in very clean water. A total of 100 insects are caught, and the total number of points is added up. Based on the stream ecology class notebook, what conclusion can you draw about the creek?
