Question
Chapter 30, Problem 1FFT
Summary Introduction
To provide: An explanation about the observation that in daytime some ectotherms body temperature would be fairly constant and also give some possible mechanisms that might be involved.
Introduction: Ectotherms are cold-blooded animals; and hence, they are able to regulate their body temperature depending on the external sources like heated rock surface or sunlight. Amphibians, fishes, invertebrates, and reptiles are some examples of ectotherms.
