Question
Which of the following animal shows double respiration ?-
- Fish
- Bird
- Both fish and bird
- Snake.
Answer
Both fish and bird
Explanation:
Both fish and bird show double respiration. Fishes use gills for respiration, and oxygen is extracted from water. Birds use lungs for respiration, and during inhalation, air passes through the lungs and then into the air sacs. During exhalation, air passes from the air sacs through the lungs and then out of the body. This allows for a continuous flow of oxygen-rich air and maximizes oxygen uptake.
