Question

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?

Answer 1
