Functional Adaptations in Animal Groups · Zoology

Endothermy in birds and mammals is advantageous because it:

  1. Greatly reduces total food requirement
  2. Sustains activity across temperatures
  3. Removes any need for body insulation
  4. Prevents nearly all body water loss
Show answer and explanation

Correct answer: Sustains activity across temperatures

Endothermy enables maintenance of constant body temperature. This allows birds and mammals to remain active across diverse climates.
