(d) A – III, B – IV, C – II, D – I
Answers
The correct option is (a) A – III, B – IV, C– I, D – II.
1. Predation- Cactus and moth
2. Commensalism- Orchid and mango
3. Parasitism- Cuscuta and hedge plants
4. Competition- Balanus and Chathamalus
* Predation- It is the feeding behaviour or biological interaction between two organisms in which one animal( predator) attacks another animal( prey) for food.
* Commensalism- It is the biological interaction such that one organism benefits whereas the other organism is neutral( neither harms not benefits).
* Parasitism- It is the interaction in which one organism lives on the other with or without harming it.
* Competition- It is the interaction between two organisms such that one tries to defeat the other.
(a) A – III, B – IV, C – I, D – II
Explanation:
A. Predation III. Cactus and Moth
The invasive cactus was brought under control only after a cactus feeding a moth (predator) from its natural habitat was introduced into the country.
B. Commensalism IV. Orchid and Mango
In Commensalism one species benefits and the other is neither harmed nor benefited such as an orchid growing as an epiphyte on a mango branch.
C. Parasitism I. Cuscuta and hedge plants
Cuscuta, a parasitic plant that is commonly found growing on hedge plants, has lost its chlorophyll and leaves in the course of evolution.
D. Competition II. Balanus and Chathamalus
The larger and competitively superior barnacle Balanus dominates the intertidal area and excludes the smaller barnacle chathamalus from the zone.
