Match List-I with List-II . List-I List-II A. Both species are harmed I. Predation B. One species is harmed and the other is benefited II. Mutualism C. Both species are benefited III. Competition D. One is benefited while the other has no effect IV. Commensalism Choose the correct answer from the options given below :

Step-by-step solution

In competition, both interacting species are harmed as they compete for the same limited resources. Thus, A matches III. In predation, one species (predator) benefits while the other (prey) is harmed. Thus, B matches I. In mutualism, both interacting species benefit from each other. Thus, C matches II. In commensalism, one species benefits while the other is neither harmed nor benefited (no effect). Thus, D matches IV. The correct matching is A-III, B-I, C-II, D-IV.
