- Dissolved oxygen (DO) can be found in an aquatic ecosystem and is often one factor that affects
the size of populations of aquatic organisms. Water temperature is very important in determining
the amount of DO in a water supply. The colder the temperature of the water, the more DO the
water can hold.
State one possible reason why the biodiversity of an aquatic ecosystem could decrease if the
water temperature were to increase. Support your answer.
