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

58. Living organisms must acquire energy from their
environment. Examples of adaptations that help
organisms acquire this energy include which of the
following?
I. The dark, heat-absorbing coloration of a
reptile.
II. The fangs and claws of a lion
III. The light coloration of a peppered moth
(A) I only
(В) П only
(C) I and II only
(D) II and III only
(E) I, II, and III
What occurs as body size increases in animals ?
there is a decrease in the surface-to-volume ratio.
reproduction becomes limited to terrestrial environments.
there is greater variability in metabolic rate.
migration to tropical areas becomes necessary for thermoregulation.
it becomes more difficult to conserve body warmth in cold environments.

It is converted to ATP molecules then used to power cellular reactions.arrow_forward
- Ecologyarrow_forwardWhich of the following is true regarding the metabolism in animals? O Metabolism is the total chemical activity, which is the sum of all anabolic and catabolic processes. O The Anabolic Pathways serve to break down molecules while the Catabolic Pathways synthesize important chemical building blocks. Through respiration, organisms obtain oxygen, whose rate is inversely porportional with the metabolic rate. O Metabolic Rate is not influenced by an organism's body temperature.
