The answer is Bass prefer warmer water.

Both trout and bass depend on water as their habitat, and they depend on it for food.  Bass can be found in warm rivers, lakes, and even stock ponds.  Trout require ice cold streams or lakes to survive and reproduce.

Organisms other than fish also may have a certain temperature range for which they are adapted.  The penguin, even though it is a bird, spends much of its lifetime in the water and is adapted to survive cold water temperatures. Some organisms, such as algae, are able to survive temperatures that reach the boiling point!
