Q. The animals that rely on the heat from the environment rather than metabolism to raise their body temperature are called ___

Q. Animals that rely on heat from the environment rather than of metabolism, to raise their body temperature are in the strict sense called

Q. In the strict sense, animals that rely only on the heat from the environment rather than on metabolism to raise their body temperature are called as

Q. Birds and mammals being homeothermic (capable of maintaining constant body temperature) have evolved a mechanism to regulate their metabolic rate. An inverse relationship is observed between metabolic rate and body weight from the plot of the rate of oxygen consumption versus body weight of different mammals. On the other hand, there is a direct proportional relationship between metabolic rate and surface area to volume ratio. From the given figure it is evident that more internal heat per gram of body weight is generated by shrew and more heat is lost to the environment than the horse. Thus maintenance of constant body temperature is more difficult for small animals in cold weather. Why do penguin chicks have to huddle together in cold environment?
