With water at a pH of 5.0, most fish eggs are unable to hatch. If the pH level continues to drop, adult animals begin to die. Experiment 1 will help you determine how sensitive brine shrimp are to acid rain.
Acidity kills plants in the water, too, thus upsetting the food chain. Even plant-eating fish that can tolerate low pH levels are soon unable to find enough to eat. With few plant-eating fish able to survive, the fish-eating fish go hungry, too.
