| S No. | Species A | Species B | Kind of interaction |
| i) | + | + | Competition |
| ii) | - | - | Predation |
| iii) | + | - | Parasitism |
| iv) | + | - | Mutualism |
| v) | + | 0 | Commensalism |
| vi) | - | 0 | Amensalism |
Which of the above correctly represents the effect on the species with the kind of interaction taking place?
The correct option is D d) Only iii, v and vi
D)
Explanation: Competition:Competition is when organisms compete for the same resources. This is a negative relationship because both organisms are harming each other.
Predation: This is where one organism hunts and eats the other organism. The organism hunting is called the predator, while the organism being hunted is called the prey.
Parasitism: Parasitism is a relationship in which one organism (the parasite) benefits while the other(the host) is harmed. This is a positive, negative relationship.
Mutualism: Mutualism is when organisms benefit from each other. This is a positive relationship.
Commensalism: Commensalism is a relationship in which one organism benefits from another organism that is not affected. This is a positive, neutral relationship.
Amensalism: Amensalism is any relationship between organisms of different species in which one organism is inhibited or destroyed while the other organism remains unaffected.
