Respiratory Adaptations: Altitude and Diving · NCERT Biology

Which adaptation reduces oxygen demand during deep diving in seals?

  1. Increasing metabolic rate to burn fuel more efficiently
  2. Selective suppression of non-essential organ activity
  3. Increasing lung ventilation rate during the dive
  4. Raising blood temperature to accelerate circulation
Show answer and explanation

Correct answer: Selective suppression of non-essential organ activity

Seals suppress activity in non-essential organs to reduce oxygen consumption. This adaptation allows longer dives.
