Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → A-IV, B-III, C-I, D-II
(A) Cuscuta and hedge plant — this matches (IV) Parasitism. Cuscuta is a parasitic plant. It takes its food from the hedge plant, which is harmed. One partner gains and the other loses.
(B) Wasp laying eggs in fig fruit — this matches (III) Mutualism. The wasp pollinates the fig flower while it lays its eggs in the ovary, and the larvae grow in the fruit. Both partners gain.
(C) Sea anemone and clown fish — this matches (I) Commensalism. The clown fish gets protection among the stinging tentacles of the sea anemone. The anemone is neither helped nor harmed.
(D) Balanus and Chathamalus — this matches (II) Competition. These two barnacles compete for space on the same rocky shore. Balanus pushes out Chathamalus.
