Question

In which among the following population interactions, both the species get benefited and both bear the loss respectively?

• A. Mutualism and predation
• B. Commensalism and competition
• C. Mutualism and parasitism
• D. Mutualism and competition

Answer 1

The correct option is D Mutualism and competition

Mutualism in brief can be defined as +/+ interaction, as both the species involved in this interspecific interaction are benefited. The association is obligatory for the existence of both of the species. Fig trees and wasps's one-to-one interaction is a beautiful example to illustrate the obligatory dependence of interaction between the plant and the insect.

Competition occurs in virtually every ecosystem in nature for similar needs of resources like food, shelter and mates often results in the survival of the fittest. Competition in brief can be defined as -/- interaction, as both the species interacting get harmed. It is a biological interaction between two organisms of the same species or different species competing for utilising the same resources. The outcome usually favours the strong competitors and has negative effects on the weaker competitors.
