Question

Gills are used for what type of respiration?

• A. Pulmonary respiration
• B. Terrestrial respiration
• C. All types of respiration
• D. None of the above

Answer 1

The correct option is D None of the above

A gill is a respiratory organ found in many aquatic organisms that extract dissolved oxygen from water and excretes carbon dioxide.complex or more active aquatic organisms usually require a gill or gills for respiration. Gills has neither terrestrial nor pulmonary respiration because terrestrial respiration refers to respiration on land and pulmonary respiration refers to respiration facilitated by lungs. Hence, respiration by gills is neither terrestrial nor pulmonary.

So, the correct option is 'none of the above'.
