Question

Commensalism is an association between two species where:

• A. one species is harmed and other is benefited
• B. one species is harmed and other is unaffected
• C. one species is benefited and other is unaffected
• D. both the species are harmed

Answer 1

The correct option is C

one species is benefited and other is unaffected

Commensalism is an interaction where one organism benefits from its relationship with another, while the other is unaffected. For eg. the clown fish and sea anemone; the clown fish uses sea anemone as home and is protected from many predators that keep away from the stinging cells of the sea anemone. The sea anemone however, is unaffected by this interaction.
