Why are bioindicators important to a water system?

• They are sensitive to pollution and tell us if the water is of good quality

• They are sensitive to pollution and tell us if the water is of bad quality

• The more bioindicators are present the better the water quality

• The fewer the bioindicators present that better the water quality
