For oxygen to dissolve in water, it needs to be soluble. Solubility is the ability of a substance to dissolve into a liquid. Oxygen can dissolve into water in multiple ways; namely, oxygen can diffuse from the atmosphere and dissolve in the water, and/or it can be introduced into water as a byproduct from the photosynthesis of aquatic plants. Wind helps with the first method, as it aerates the water, which helps the oxygen to dissolve. Since dissolved oxygen is needed by all forms of aquatic life, it is often used as one measure to determine the health of bodies of water. What do you think would happen if there was not enough dissolved oxygen in a lake?

Question

Transcribed Image Text:2. For oxygen to dissolve in water, it needs to be soluble. Solubility is the ability of a substance to dissolve into a liquid. Oxygen can
dissolve into water in multiple ways; namely, oxygen can diffuse from the atmosphere and dissolve in the water, and/or it can be
introduced into water as a byproduct from the photosynthesis of aquatic plants. Wind helps with the first method, as it aerates
the water, which helps the oxygen to dissolve.
Since dissolved oxygen is needed by all forms of aquatic life, it is often used as one measure to determine the health of bodies of
water.
What do you think would happen if there was not enough dissolved oxygen in a lake?
There would be no effect on the lake.
Fish would not get enough oxygen and could die.
The diversity of aquatic organisms would increase.
