- C.Sea Anemone and Clown fish
- D.Female wasp and fig species✓
Correct Answer
(D) Female wasp and fig species
Solution & Explanation
Answer: (D) Female wasp and fig species. The question asks which is NOT commensalism. Orchid on a tree (epiphyte), cattle egret with grazing cattle, and sea anemone with clown fish are all classic examples of commensalism (one benefits, the other unaffected). The female wasp and fig relationship is obligate mutualism (the fig is pollinated by the wasp and the wasp's larvae are nourished by developing seeds - both benefit), not commensalism. Hence answer D. NCERT: Ch 11, p.201, lines 9-10 — "An orchid growing"
