Question

Commensalism is a symbiotic relationship between two organisms where

• A. Both partners benefit
• B. One partner benefit and causes harm to other
• C. One partner benefits and the other receives no harm
• D. Both partners are disadvantaged

Answer 1

The correct option is C One partner benefits and the other receives no harm

Commensalism is a long-term biological interaction in which members of one species gain benefits while those of the other species neither benefit nor are harmed. In other words, this is a one-sided symbiotic relationship. The relationship between tigers and golden jackals is also commensalism. The jackal alerts the tiger to a kill and feeds on the remains of the prey left by the tiger.

So, the correct answer is 'C'.
