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

In ecological systems, a rough rule of thumb is that when energyis transferred from plants to plant-eaters or from preyto predator, the efficiency is only about 10% (p. 72). Muchof this inefficiency is a consequence of the second law ofthermodynamics. Another way to think of this is that eating 1calorie of material from an animal is the ecological equivalentof eating 10 calories of plant material.Humans are considered omnivores because we can eat bothplants and animals. 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.
What percentages of the calories in your own diet do youthink come from plant versus animal sources? Estimatethe ecological impact of your diet, relative to a strictlyvegetarian one.

- Grasses collect energy from sunlight. Rabbits collect energy by eating grasses. Coyotes collect energy by eating rabbits. Which of the following organisms has the least amount of energy available to them (as compared to the amount of solar energy that hits Earth from space)? A.

The world record for assisted free diving is held by Pipin Ferreras, who dove 170 m (558 ft) with the aid of a sled. Free diving is not without its dangers. Pipin’s wife Audrey died during a world record attempt. Free diving is facilitated by the dive reflex, which allows mammals to hold their breath for long periods of time underwater. Immersing one’s face in cold water includes bradycardia and diverts blood away from the periphery. How would these modifications increase the ability to free dive?arrow_forwardHibernating bears lose up to 30% of their body mass over the winter. Where does that body mass go? It is converted to CO₂ and H₂O in cellular respiration and then excreted from the bear's body. It is converted to heat and then lost to the environment. It is converted to ATP molecules then used to power cellular reactions.arrow_forward
