How do benthic macroinvertebrates indicate water quality?

• If pollution-intolerant organisms are found, quality is good.
  

• If pollution-intolerant organisms not found, water is poor.

• If pollution-tolerant organisms are found, quality is good.

• If any of these are found, water is of poor quality.

The presence of only pollution tolerant macroinvertebrates like aquatic worms and black fly larva indicates

• good quality water

• poor quality water

• fair quality water

• swimming pool water

The presence of a pollution intolerant macroinvertebrate like a water penny indicates

• good quality water

• poor quality water

• fair quality water

• a polluted pond
