QUESTION
Commensalism denotes?
OPTIONS
(A) Association between two species without either being metabolically dependent without harm
(B) Association between two species which harm each other
(C) All of the above
(D) None of the above
ANSWER
(A) Association between two species without either being metabolically dependent without harm
EXPLANATION
Commensalism is an association in which one organism benefits while the other is neither significantly benefited nor harmed; neither organism is metabolically dependent on the other in the strict sense. An association in which both are harmed is not commensalism, so the other choices are incorrect.
