Question

Which one of the following is not a characteristic of large sized animals?

• A. High BMR
• B. Longer generation time
• C. Lower reproductive rates
• D. Slower growth rates

Answer 1

The correct option is A High BMR

Smaller endothermic animals have a greater surface area for their mass than larger ones. Therefore, smaller animals lose heat at a faster rate than larger animals and require more energy to maintain a constant internal temperature. This results in a smaller endothermic animal having a higher BMR, per body weight, than a larger endothermic animal.
