Match List-I with List-II regarding predation and defence mechanisms. List-I List-II (A) Calotropis (I) Thorns (B) Acacia (II) Cardiac glycosides (C) Monarch butterfly (III) Feed on plant sap and other parts (D) Phytophagous insects (IV) Highly distasteful due to a special chemical Choose the correct answer from the options given below:

Options

  1. A(A)-(II), (B)-(I), (C)-(IV), (D)-(III)
  2. B(A)-(I), (B)-(II), (C)-(IV), (D)-(III)
  3. C(A)-(II), (B)-(I), (C)-(III), (D)-(IV)
  4. D(A)-(IV), (B)-(I), (C)-(II), (D)-(III)

Correct answer

A. (A)-(II), (B)-(I), (C)-(IV), (D)-(III)

Step-by-step solution

Calotropis produces highly poisonous cardiac glycosides as a chemical defence against herbivores. Acacia possesses thorns as a morphological means of defence. The Monarch butterfly is highly distasteful to its predators due to a special chemical present in its body, acquired during its caterpillar stage. Phytophagous insects are those that feed on plant sap and other parts of plants. Therefore, the correct match is (A)-(II), (B)-(I), (C)-(IV), (D)-(III). Answer: (A)-(II), (B)-(I), (C)-(IV), (D)-(III)
