Now you should be able to explain in your own words how water is distributed on Earth.

Multiple Choice

Bioindicators are living organisms that indicate if a body of water is healthy or not.

• true 

• false

Multiple Choice

Look at the image.  Which one represents high turbidity? Remember, turbidity is the cloudiness of water.

• clear

• murky

Multiple Choice

Imagine a fish swimming in murky water. Water that has high turbidity. Choose below how you think the water will be affected. 

• The temperature will increase and reduce the dissolved oxygen for the aquatic life. The fish gills will get clogged.

• the aquatic life will thrive and increase

Multiple Choice

Which does an increase in eutrophication indicate to scientists studying a body of water?

• an increase in fertilizer runoff

• a decrease in pollutants from farm runoff

• an increase in the health of the body of water

• an increase in oxygen levels in the body of water

Multiple Choice

What happens to the fish in water if the temperature is hot?

• It will increase the dissolved oxygen, and they will live happily ever after.

• Hot water, especially if it is 35 degrees Celsius or higher, reduces dissolved oxygen for fish. Fish will suffocate and die.

• They will be just right for dinner.

Multiple Choice

When the PH of water is 7, is it safe for aquatic life?

• true

• false
