When a person breathes in the air, the air enters into his body through an organ A having two holes B in it. The air then passes through the pharynx and larynx and enters into tube C. The tube C divides into two smaller tubes D at its lower end. The two smaller tubes are attached to two respiratory organs E. Each smaller tube divides inside the organs E to form a large number of still smaller tubes called F. The smallest tubes F have air-sacs G at their ends in which gaseous exchange takes place in the body of the person. What are A, B, C, D, E, F, and G?
An organism X having breathing organs A lives on land. When organism X goes underwater, it cannot survive for a long time unless carrying an oxygen cylinder. On the other hand, the organism Y having breathing organs B always lives in water and if taken out of the water, it dies after a short while. A third organism Z having breathing organs C and D which lives on the banks of ponds, lakes, and rivers can survive on land as well as in water equally well.
(a) What could organism X be? Name the breathing organs A.
(b) What could organism Y be? Name the breathing organs B.
(c) What could organism Z be? Name the breathing organs C and D.
(d) Out of X, Y, and Z, which organism is (i) amphibian, (ii) aquatic, and (iii)
terrestrial?
