Countercurrent heat exchangers are more useful for
ectotherms to allow their body temperature to match the environment
endotherms to allow the body's core temperature to remain stable
endotherms to allow their extremities to remain at an elevated body
temperature in the cold
poikilotherms that need to have different body temperatures
ectotherms to permit them to maintain constant body temperature
The main difference between ectotherms and endotherms is
how they obtain food to provide for their metabolism.
the source of their body heat.
whether they conserve or eliminate body heat.
whether they control their body temperature.
Which of the following statements best summarizes the difference between ectothermic and endothermic organisms?
Group of answer choices
Ectotherms absorb external heat, but endotherms use metabolic heat to maintain a warm, steady body temperature
Ectotherms are warm-blooded, but endotherms are cold-blooded
Endotherms control their temperature, but ectotherms have no control over their temperature
Endotherms are warm-blooded, but ectotherms are cold-blooded
