Question

Aquatic organisms are able to survive when the temperature decreases. These organisms survive even when the surfaces of lakes and ponds are covered with ice. Which property of water best explains how aquatic organisms can survive during freezing temperatures?

Answer 1

Anomalous expansion

Step-by-step explanation:

Anomalous expansion of water is the abnormal way water expands when exposed to low temperature.

At 4 degree Celsius , the density at the top layer is usually at the Maximum which makes the water sinks down and then the water in the lower layer rises up.

When the temperature drops below 4 degree Celsius, the water molecules at the top then freezes leaving the denser molecules at the bottom which doesn’t freeze as a result of their high density.

This way, organisms can survive in the water due to the lower layer not freezing.
