In terrestrial organisms, what is the respiratory surface like to reduce water loss?
Answer and explanation
Correct answer: Protected inside the body
Terrestrial organisms obtain oxygen from air, but an exposed moist respiratory surface would allow water to evaporate rapidly. Natural selection and body organization therefore commonly place the respiratory surface inside protected structures, such as lungs or tracheal systems, while still providing a thin area for diffusion. Option A is correct. A completely open and dry surface would hinder diffusion, and the remaining choices are not general features of terrestrial respiration.
