Statement 1: Amphibians often hibernate in winter and aestivate in summer.
Statement 2: They are poikilothermic animals and cannot regulate body temperature.

Correct Answer: b. Statement 1 is correct.

Explanation:

Amphibians and Hibernation:
- Hibernation is a state of inactivity and reduced metabolic activity that some animals enter during the winter months.
- Amphibians, such as frogs and toads, often hibernate during winter.
- Hibernation allows amphibians to conserve energy and survive the cold temperatures when food sources are limited.
- During hibernation, amphibians become less active, their heart rate slows down, and their body temperature drops to match the surrounding environment.

Amphibians and Aestivation:
- Aestivation is a state of inactivity and reduced metabolic activity that some animals enter during hot and dry periods, typically in summer.
- Amphibians, especially those living in arid or tropical regions, may aestivate during periods of extreme heat or drought.
- Aestivation allows amphibians to conserve water and energy by staying buried in the ground or finding shelter in cool and moist areas.

Poikilothermic Animals:
- Amphibians are poikilothermic animals, also known as cold-blooded animals.
- Unlike warm-blooded animals (endothermic), such as mammals and birds, amphibians cannot regulate their body temperature internally.
- Instead, their body temperature fluctuates with the temperature of their environment.
- This means that amphibians rely on external sources, such as the sun or shade, to warm or cool their bodies.

Conclusion:
- Statement 1 is correct as amphibians often hibernate in winter and aestivate in summer.
- Statement 2 is incorrect as amphibians are poikilothermic animals and cannot regulate their body temperature internally.
