Which best describes the relationship between temperature and dissolved oxygen in a lake? As temperature increases, dissolved oxygen increases.
As temperature increases, dissolved oxygen decreases.
As temperature decreases, dissolved oxygen decreases.
A change in temperature has no
effect on dissolved oxygen.

Explanation:

Air and Water Temperature Increases

For example, increases in water temperatures are expected to result in the following: Lower levels of dissolved oxygen due to the inverse relationship that exists between dissolved oxygen and temperature. As the temperature of the water increases, dissolved oxygen levels decrease.
