Balance & Body Size
Smaller animals have a higher ratio of this to volume, which drives their elevated mass-specific metabolic rate.
What is surface area?
A common household pet that maintains constant body temperature
What is a dog?
This type of animal generates its own body heat internally.
What is an endotherm?
These are the three types of balance equations studied in animal physiology.
What are energy, water, and thermal balance?
Fuel source when RQ is close to 1
What are carbohydrates?
This term describes an animal that maintains a relatively constant internal body temperature.
What is a homeotherm?
This percentage of energy is typically lost through feces and urine and is NOT available for metabolism.
What is digestive efficiency loss?
Unit that measures oxygen consumption per body mass and time
What is ml O₂/kg/hr?
A shark is this type of thermoregulator.
What is an ectotherm or poikilotherm
Smaller animals must do this more to maintain body temperature
What is "eat more" or "increase metabolism"
Relationship showing metabolic rate scaling with body size.
What is Kleiber’s Law?
This temperature zone is where a homeotherm expends the least energy on thermoregulation.
What is the thermoneutral zone
This type of metabolic rate is higher in smaller animals
What is mass-specific metabolic rate?
This process increases heat production in cold conditions
What is shivering?
This curve shape shows metabolism lowest at moderate temperatures
What is a U-shaped curve
