In pollination ecology, reducing scent after pollination serves to

• A. To maximize pollination efficiency by directing pollinators to unpollinated flowers
• B. To conserve energy
• C. To attract different pollinator species
• D. To increase nectar production

Answer: (A)

Floral scent acts as both an attractant and a signal about a flower’s reward status. After a flower has already been pollinated, lowering its scent reduces its attractiveness, nudging pollinators to move on to other flowers that still need pollen. This targeted change helps maximize the chance that pollinators visit unpollinated flowers, increasing the overall efficiency of pollen transfer and the plant’s reproductive success. While reduced scent might save energy in theory, the main idea is directing pollinator flow to flowers that still require pollination, rather than attracting different pollinators or boosting nectar production.
