Question

Between which among the following, the relationship is not an example of common symbiosis?

• A. Orchid and the tree on which it grows
• B. Cattle egret and grazing cattle
• C. Sea anemone and clownfish
• D. Female wasp and fig species

Hint:

Symbiosis encompasses diverse relationships like mutualism, commensalism, and parasitism. Examples include species interactions benefiting both (mutualism) or one (commensalism) while harming none.

Answer 1

The Correct Option is D

Step 1: Define symbiosis and analyze provided examples.

Symbiosis is a prolonged, intimate biological association between distinct organisms. This interaction can be classified as mutualistic (both benefit), commensalistic (one benefits, the other is unaffected), or parasitic (one benefits at the other's expense). The objective is to identify the example that deviates from a standard symbiotic scenario.

- Option (A): The interaction between an orchid and its host tree exemplifies commensalism. The orchid gains access to sunlight by growing on the tree without causing harm.

- Option (B): The relationship between a cattle egret and grazing cattle is mutualistic. The cattle disturb insects as they graze, making them accessible food for the egret.

- Option (C): The association between a sea anemone and a clownfish is mutualistic. The clownfish receives protection from predators, and the anemone benefits from the clownfish's waste, which provides nutrients.

- Option (D): The relationship between a female wasp and a specific fig species represents a specialized mutualism centered on reproduction (pollination), rather than a general symbiosis example.

Step 2: Determine the correct answer.

Although all presented options describe ecological interactions, option (D) describes a highly specialized reproductive mutualism, distinguishing it from common instances of general symbiosis. Therefore, it is the appropriate answer.
