A) antibiosis
B) commensalism
C) predation
D) parasitism
Correct Answer: B
Solution :
In commensalism, association between members of different species is made in the way that one is benefitted and neither is harmed, eg, small fish (sucker fish) gets stucs near the bottom of a shark with the help of is hold fast (modified dorsal fin) and is dispersed to distant areas. It also gets protection (due to association with shark) and derive its nutrition also. However, the shark does not get any benefit or harm form the sucker fish. Antibiosis refers to the complete or partial inhibition of one organism by another through the production of some substance of environmental conditions as a result of metabolic pathways. In parasitism the parasite organisms derives food and sometimes shelter also, from the host without killing it. In predation, predatory organisms are free living which catch and kill another species for food.
