Temperature (Degrees Celcius)


Temperature plays an important role in aquatic ecosystems. It is responsible for creating the different layers of stratification in lakes: epilimnion, metalimnion, and hypolimnion. In the hypolimnion, the temperature never drops below 4 degrees Celcius, unless the lake is extremely shallow. Warmer water contains less dissolved oxygen than colder water, so temperature determines the dissolved oxygen content of aquatic systems.
