Question

In a population interaction between the species X and the species Y, which one of the following statements is correct?

• A. When X benefits and Y is disadvantaged, it is Competition
• B. When both X and Y benefit, it is Mutualism
• C. When both X and Y are disadvantaged, it is Predation
• D. When both X and Y are disadvantaged, it is Parasitism

Answer 1

Answer: (B)

When both X and Y benefit, it is Mutualism

Competition is a relationship between two species in which both the species compete for the same resource or territory. The fitted out of two is benefited. Mutualism is a relationship between two species in which both species are benefited from the interaction. Parasitism is a relationship between two species in which one species (the parasite) is benefited and the other species (the host) is harmed. Predation is a relationship between two species in which one species (the predator) kills the other species (the prey) to obtain food.

Thus, the correct answer is option B.
