Water Quality Indicators

Discover water quality indicators! Learn about pH, turbidity, and more to understand water health.

Water Quality Indicators Match the water quality indicator with the picture that shows the meaning of the indicator. pH color bio-indicator temperature turbidity Many home cleaning products contain phosphates. If wastewater containing excess phosphates drains into a pond, the phosphates encourage the growth of algae. How might this change in a pond's ecosystem affect the quality of life for other living things in the pond? Other water plants might have less light to help them grow. Some algae produce toxins, so the water could be poisoned. Fish, like carp, that eat algae will have more food. all of these Some factors affecting water quality include clarity, chlorophyll level, and dissolved _. hydrogen oxygen helium sunlight What effect does turbidity have on an aquatic system? It has no effect on water temperature but impairs photosynthesis. It decreases dissolved oxygen levels and impairs photosynthesis. It has no effect on water temperature and can suffocate fish eggs and insect larvae. It increases dissolved oxygen increases plant growth Does cold water hold more, less, or exactly the same amount of dissolved oxygen as warm water? more less exactly the same What pH level does MOST aquatic life function BEST at? 3-5.5 pH 9-10 pH 6.5-9 pH 5-8 pH Sort the words into the correct category.
