A

antibiosis

B

commensalism

C

predation

D

Text Solution

Verified by Experts

The correct Answer is:
B
In commensalism, association between the members of different species is made in the way that nor one is benefitted and neither is harmed. For example, small fish (sucker fish) gets stuck near the bottom of a shark with the help of its holdfast (modified dorsal fin) and is dispersed to distant area. It also gets protection due to association with shark and derives its nutrition also. However, the shark does not get any benefit or harm from the sucker fish.
