Zoology - Organisms and Populations Question with Solution | TestHub

Both the species benefit in mutualism and both lose in competition in their interactions with each other. In both parasitism and predation, only one species benefits (parasite and predator, respectively) and the interaction is detrimental to the other species (host and prey, respectively). The interaction where one species is benefitted and the other is neither benefitted nor harmed is called commensalism. In amensalism, one species is harmed whereas the other is
unaffected.
