Match each organism with the type of association it exhibits. (letters to numbers) (a) barnacles on the back of a whale (b) a stork eating fish with its beak (c) ticks sucking the blood from the body of an animal (1) prey-predator (2) parasitism (3) commensalism

Ans.

Biological interactions or ecological interactions are defined as relationships that affect two organisms of same or different species living in a community. Different types of association are observed in different organisms.

Barnacles and whale show a type of symbiotic relationship, in which barnacles get benefit from association, without causing any harm to whale. This type of association is known as commensalism. Thus, option A). correctly matches with option 3). commensalism.

A stork and fish shows prey-predator relationship, where stork is predator that feeds on small fishes (preys). In this kind of relationship one species gets benefits, while other gets harm. Thus, option B). correctly matches with option 1). prey-predator.

A tick sucking the blood from an animal body shows a kind of symbiotic association, known as parasitism. The tick (parasite) lives inside inside or on the body of another organism (host) to get benefit and causes harm to the host. Thus, option C). correctly matches with option 2). parasitism.
