Which one of the following relationships would be considered a win/win?
mutualism commensalism parasitism predation
The relationship that would be considered a win/win is mutualism. In mutualism, both species involved benefit from the interaction. For example, bees and flowering plants have a mutualistic relationship where bees get food (nectar) from the flowers, and in return, they help pollinate the plants.
In contrast, commensalism involves one species benefiting while the other is neither helped nor harmed, parasitism involves one species benefiting at the expense of the other, and predation involves one species benefiting (the predator) while the other is harmed (the prey).
