Respiratory Adaptations: Altitude and Diving · NCERT Biology

Which statement best summarizes respiratory adaptations in high altitude and underwater environments?

  1. Both rely on increased oxygen concentration in surroundings
  2. Both involve reduced respiratory surface area
  3. Both enhance oxygen uptake under low availability
  4. Both eliminate the need for specialized respiratory organs
Show answer and explanation

Correct answer: Both enhance oxygen uptake under low availability

Both environments present low oxygen availability. Organisms adapt by improving oxygen uptake and utilization efficiency.
