Which one of the following is an appropriate example of 'sexual deceit' ?

A Female wasp and fig
B Ophrys and bumblebee
C Sea anemone and clown fish
D Cuckoo and crow

Verified Solution

Answer & Solution

Correct Answer

(B) Ophrys and bumblebee

Step-by-step Solution

Detailed explanation

(B) Ophrys and bumblebee
The Mediterranean orchid Ophrys employs 'sexual deceit' to get pollinated by a species of bee. One petal of its flower bears an uncanny resemblance to the female of the bee in size, colour, and markings. The male bee is attracted to what it perceives as a female, 'pseudocopulates' with the flower, and during that process is dusted with pollen from the flower. When this same bee 'pseudocopulates' with another flower, it transfers pollen to it and thus, pollinates the flower.
Female wasp and fig exhibit mutualism.
Sea anemone and clown fish exhibit commensalism.
Cuckoo and crow exhibit brood parasitism.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
