Final answer:
Yes, lupins do produce nectar to attract pollinators and promote seed production.
Step-by-step explanation:
Yes, lupins do produce nectar. Nectar is a sweet liquid produced by many flowering plants to attract pollinators such as insects, birds, and mammals. Lupins have adapted to attract specific pollinators by having structures like long tubular flowers that prevent other pollinators from accessing the nectar, ensuring cross-pollination within their own species. The presence of nectar in lupins plays an important role in influencing pollinator behavior and promoting seed production.
