Chapter 40, Problem 2SYK

Summary Introduction

To explain: The reason why ectotherm has the ability to tolerate wider internal temperature fluctuations and endotherms may be able to tolerate wider external temperature fluctuations.

Introduction: Endotherms are animals that mostly gain heat from the environment. For example, the majority of fishes, invertebrates, nonovarian reptiles, and amphibians. Cold-blooded organisms are referred to as ectotherms. These animals regulate the temperature of the body based on the external sources. For example, a heated rock surface or sunlight. The ectotherms include amphibians, fishes, invertebrates, and reptiles.
