| (B) | Gills | (II) | Insects centipedes |
| (C) | Trachea | (III) | Fish |
| (D) | Airsacs | (IV) | Mammals |
Choose the most appropriate answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → (A)-(IV), (B)-(III), (C)-(II), (D)-(I)
Each animal group has a breathing organ suited to where it lives and how much oxygen it needs.
(A) Lungs — this matches (IV) Mammals. Mammals breathe air through a pair of lungs, where oxygen passes into the blood through millions of tiny air sacs called alveoli.
(B) Gills — this matches (III) Fish. Gills take in the oxygen dissolved in water as it flows over their thin, blood-rich filaments.
(C) Trachea — this matches (II) Insects centipedes. Insects and centipedes have a network of air tubes (tracheae) that open through spiracles and carry air straight to the body cells.
(D) Airsacs — this matches (I) Birds. Birds have lungs plus a set of air sacs that keep air flowing one way through the lungs, giving the steady oxygen supply that flight needs.
