Why do aquatic species feel more comfort...

Why do aquatic species feel more comfortable in the lakes in winter than in summer ?

Text Solution

Verified by Experts

Aquatic species need dissolved oxygen for breathing. As solubility of gases decreases with increases of temperature, less oxygen is available in summer in the lakes. Hence, they feel more comfortable in winter (low temperature) when the solubility is higher.
