Answer:
coevolution
Explanation:
Male euglossine bees harvest the pollen and fragrance compounds from orchids, typically a specific species, and display these in various ways. The female euglossine bee is thought to choose a mate based on the quantity and/or quality of fragrance mixtures presented. The orchids pollinated by these bees have evolved elaborate trapping mechanisms that will often only allow a single species of bee to enter and collect the fragrance; the trap will then force the bees to exit in a way that attaches the orchid's pollen to them. The elaborate courtship ritual and flower development both act to enhance the reproductive success of the insect and orchid, respectively. This is an example of coevolution.
Coevolution occurs when two or more species reciprocally affect each other's evolution.
