Sample Question 1
How does thermal energy move between an animal and its environment?

Thermal energy is produced by the animal and stays within its body.

Thermal energy moves down a temp. gradient from the animal to environment or vice versaTotal thermal energy = Sum of each of the following:MetabolismConduction: Transfer of thermal energy from an object or fluid to anotherVaries w/ the type of material & geometryWater has very high thermal conductivityConvection: Transfer of thermal energy b/n an object & external medium that is movingRadiation - Emission of electromagnetic radiationEvaporation - Water molecules absorb thermal energy from a surface when making the transition from liquid to vapor

Thermal energy is not affected by temperature differences.

Thermal energy always moves from the environment to the animal.

Sample Question 2
What are the two main thermal strategies used by organisms?

Hibernation and Migration

Acclimatization and Adaptation

ToleranceBody temperature is allowed to vary w/ ambient temperatureRegulationBody temperature does not vary w/ ambient temperatureBoth strategies have costs & benefits

Photosynthesis and Respiration

Sample Question 3
Thermal Tolerance of Animals

Stenotherms can adapt better to varying temperatures compared to eurytherms

Eurytherm: Can tolerate a wide range of ambient temperaturesStenotherm: Can tolerate only a narrow range of ambient temperaturesTherefore, eurytherms can occupy a greater # of thermal niches than stenotherms

Eurytherms are more sensitive to temperature changes than stenotherms

Eurytherm: Can only tolerate high temperatures Stenotherm: Can tolerate any temperature range equally well
