Select the wrong statement w.r.t. stenothermal.
Solution:
Stenothermal organisms are those that can tolerate only a narrow range of temperatures.
Statement (1) is correct: Organisms restricted to a narrow temperature range would naturally thrive in environments where the temperature remains relatively uniform throughout the year.
Statement (2) is correct: This is the definition of stenothermal organisms.
Statement (3) is incorrect: Stenothermal organisms can be both warm-blooded (homeothermic) and cold-blooded (poikilothermic). For example, polar bears (mammals, which are warm-blooded) are stenothermal as they are adapted to a very narrow, cold temperature range. Many fish (cold-blooded) are also stenothermal. Therefore, the statement that only cold-blooded animals belong to this category is wrong.
Statement (4) is correct: Polar bears are mammals adapted to extremely cold and specific temperature conditions, making them stenothermal.
