Match List-I with List-II regarding ecological competition and its outcomes. List-I List-II (A) Resource partitioning (I) Paramecium aurelia and Paramecium caudatum (B) Competitive exclusion (II) Flamingoes and resident fishes in South American lakes (C) Competitive release (III) Five closely related species of warblers (D) Interference competition (IV) Balanus and Chthamalus on the rocky sea coasts of Scotland Choos

Options

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

Correct answer

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

Step-by-step solution

(A) Resource partitioning is demonstrated by MacArthur's study on five closely related species of warblers that avoided competition through different foraging behaviours. (B) Competitive exclusion is illustrated by Gause's experiment where Paramecium aurelia outcompeted and eliminated Paramecium caudatum. (C) Competitive release was shown by Connell's field experiments where the removal of the superior barnacle Balanus allowed the inferior Chthamalus to expand its niche. (D) Interference competition occurs when the
