|---|---|
| Organisms | Types of interaction |
| (A) Barnacles Balanus and Chthamalus in the intertidal area | (I) Mutualism |
| (B) Orchid growing on a mango branch | (II) Competition |
| (C) Plants and herbivores | (III) Predation |
| (D) Mycorrhiza between fungi and roots of higher plants | (IV) Commensalism |
Choose the correct answer from the options given below.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (A)-(II), (B)-(IV), (C)-(III), (D)-(I)
(A) Barnacles Balanus and Chthamalus in the intertidal area — this matches (II) Competition. On the Scottish coast the larger, competitively superior Balanus excludes the smaller Chthamalus from the intertidal area.
(B) Orchid growing on a mango branch — this matches (IV) Commensalism. The orchid gets support and light, while the mango tree gains nothing and loses nothing (+/0).
(C) Plants and herbivores — this matches (III) Predation. For plants, herbivores are the predators: they eat parts of the plant.
(D) Mycorrhiza between fungi and roots of higher plants — this matches (I) Mutualism. The fungus passes minerals to the plant, and the plant gives the fungus carbohydrates (+/+).
