Biology Final Review

The symbiotic relationship between a flower and the insect that feeds on its nectar is an example of

• mutualism because the flower provides the insect with food, and the insect pollinates the flower

• parasitism because the insect lives off the nectar from the flower

• commensalism because the insect doesn’t harm the flower, and the flower doesn’t benefit from the relationship

• predation because the insect feeds on the flower
