Darwin observed an orchid flower with petals arranged in very long, thin tubes, rather than broad and flat, as we might see in other common flowers. What is the advantage to the orchid having an 11-inch-long nectar tube arrangement of the petals? A. The flower can produce nectar more easily spread over a larger area to attract more pollinators.B. The flower can only be pollinated by o specifically adapted pollinator, reducing cross fertzation among orchid species.C. The flower nectar tube can collect more romwater to mainain health of the lower.D. The long tube can trap insects as a source of nutrients.

Orchids typically have relationships with their pollinators. These are usually bees, wasps, and flies but many orchids also utilize moths, butterflies, fungus, or birds to cross-pollinate their flowers.

The orchid flower can only be pollinated by a specifically adapted pollinator, reducing cross-fertilization among orchid species.

How the orchids are pollinated?

Orchids are not pollinated by wind or water. With the exception of self-pollinated ones, especially certain terrestrial species, they are pollinated mostly by animals, mainly insects.

The main orchid pollinators are bees and other Hymenoptera, some flies, and hummingbirds.

Therefore, the correct option is B that orchids are specifically adapted pollinators, reducing cross-fertilization.
