उत्तर
The type of interaction between ‘clown’ fish and sea anemone is called commensalism.
Commensalism is the interaction where one partner gets benefited while the other one is not affected in any way.
In this case, clownfish get protection and hence it is benefited while sea anemone is not affected in the course of interaction.
