Question

All interactions show a kind of relationship between two organisms in which one is benefited at the expense of other except

• A. Competition
• B. Herbivory
• C. Predation
• D. Parasitism
• E. Commensalism

Answer 1

The correct option is E Commensalism

Commensalism is a type of interaction between two organisms in which one organism is benefited while the other remains unaffected from the interaction.

One of the common examples is Barnacles attached to the whales. Barnacles are sessile and they get benefit from whales which transports them and thereby helps in feeding them and in turn whales are neither harmed nor benefited with this association. Hence, the correct answer is option E.
