A) heterothermic
B) homoeothermic
C) endothermic
D) poikilothermic
Correct Answer: D
Solution :
Poikilothermic or cold blooded animals are those animals, which change their body tempe- rature according to environmental tempe- rature, eg, fishes, amphibians and reptiles. Heterothennic are organisms, which have ability to regulate their body temperature intermediate between an endotherm and an ectotherm. The body temperature of homoeothermic (warm blooded) animals normally remains almost constant in au seasons, eg, birds and mammals. They are also known as endothermic.
