Question
Chapter 40.4, Problem 3CC
Summary Introduction
To explain: The changes in the metabolic rate in an alligator and a lion resting in a zoo, when at night the air temperature lowers down.
Concept introduction:
Thermoregulation is an ability of an organism to maintain its body temperature. Animals are categorized into two types based on their thermoregulation mode: ectotherms and endotherms. Ectotherms are animals that get warmed by external sources, whereas endotherms maintain their body temperature based on internal

Muchof this inefficiency is a consequence of the second law ofthermodynamics.

Our food choices have significant ecologicalimpacts. With this in mind, calculate the ecologicalenergy requirements for four different diets, each of whichprovides a total of 2000 dietary calories per day.
