Question

Given below are two statements:
Statement (I) : Ectotherms are temperature conformers.
Statement (II) : Homeotherms are temperature regulators.
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both Statement (I) and Statement (II) are correct.
• B. Both Statement (I) and Statement (II) are incorrect.
• C. Statement (I) is correct but Statement (II) is incorrect.
• D. Statement (I) is incorrect but Statement (II) is correct.

Hint:

To remember this: - Conformers (Ectotherms) = Body temperature follows (conforms to) the environment.
- Regulators (Homeotherms/Endotherms) = Keep body temperature stable through internal regulation.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Animals are classified into different groups based on how they manage their internal body temperature in response to changing environmental temperatures.

Step 2: Detailed Explanation:
Statement (I) describes ectotherms as temperature conformers.
Ectotherms (such as reptiles, amphibians, and fish) do not generate enough metabolic heat to maintain a constant body temperature.
Their body temperature rises and falls with the temperature of their surroundings.
Because their internal temperature conforms to the external environment, they are classified as temperature conformers.
Thus, Statement (I) is correct.
Statement (II) describes homeotherms as temperature regulators.
Homeotherms (such as birds and mammals) generate heat through metabolic activity and use regulatory mechanisms (like sweating, panting, or shivering) to maintain a stable core body temperature despite changes in external conditions.
Because they regulate their internal environment, they are classified as temperature regulators.
Thus, Statement (II) is correct.

Step 3: Final Answer:
Both Statement (I) and Statement (II) are correct.
