Match the columns, I, II, and III with reference to adaptation.
| Column I (Type of adaptation) | Column II (example) | Column III (Characteristic / Activity) |
|---|---|---|
| A. Behavioural | p. Seal | i. Crassulacean acid metabolism |
| B. Morphological | q. Desert Lizard | ii. Have thick layer of blubber below skin |
| C. Physiological | r. Photosynthetic pathway | iii. bask in sun and absorb heat |
Options:
Answer:
Solution:
Desert lizards manage their body temperature by behavioural means. They bask in the sun and absorb heat when their body temperature drops below the comfort zone, but move into shade when the ambient temperature starts increasing. This is a behavioural adaptation (A q iii).
In polar seas, aquatic mammals like seals have a thick layer of fat (blubber) below their skin that acts as an insulator and reduces loss of body heat. This is a morphological/anatomical adaptation (B p ii).
Many desert plants have a special photosynthetic pathway (Crassulacean acid metabolism or CAM) that enables their stomata to remain closed during day time to minimise water loss. This is a physiological adaptation (C r i).
