What is the relationship between two organisms in which one organism benefits and the other is unaffected?

Show answer & explanation

Correct answer: B

Explanation

The correct answer is Option 2 i.e. Commensalism

  • In commensalism, two species have a long-term interaction that is beneficial to one and has no positive or negative effect on the other (+/0 interaction).
  • In Mutualism, a symbiotic relationship between two species in which both partners benefit.
  •  In Competition, two species compete for the same limited resource. Competition has a negative effect on both of the species.
  • Predation is a biological interaction where one organism (predator) kills and eats another organism (prey). This interaction is positive for the predator and negative for the prey (+/- interaction).
