Which of the following is an ectothermic animal?
Show Hint
Ecto = External. Ectotherms get heat from external sources (like the sun).
Updated On: May 5, 2026
- Mammals
- Birds
- Reptiles
- None of these
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Animals are categorized as ectotherms or endotherms based on how they regulate their body temperature.
Step 2: Meaning
Ectotherms (cold-blooded) rely on external environmental sources to regulate body heat, whereas endotherms (warm-blooded) generate heat internally.
Step 3: Analysis
Mammals and birds are endotherms that maintain a constant internal temperature. Reptiles, amphibians, and most fish are ectotherms whose body temperature fluctuates with their surroundings.
Step 4: Conclusion
Reptiles often bask in the sun to gain heat, making them a classic example of ectothermic animals. Final Answer: (C)
