Sundew (Drosera spp.) is a carnivorous plant that traps insects with sticky leaves. Sundew faces a challenge in attracting pollinators without trapping them. Two sundew species utilize the same pollinators, but D. cistiflora produces its flowers on a tall stalk, while D. pauciflora has a shorter flower stalk. A study was carried out to determine whether the benefit of placing flowers on a long stalk is to reduce accidental predation of pollinators or to attract pollinators more effectively. First, plants were observed in their natural environments and counts were made of the number of pollinators and prey on each species. please type A B C D
Number of pollinators Less than 5 mm More than 5 mm 8 492 11 489 Number of prey Less than 5 mm More than 5 mm 274 311 lo D. cistiflora D. pauciflora Then, flower stalks from both species were cut and placed in small test tubes. The tubes were then placed in the natural environment, with some perched above the foliage and some buried to near ground level. The number of pollinators that visited each was recorded. Flowers above foliage 250 402 Number of pollinators Flowers near ground level 31 28 D. cistiflora D. pauciflora the conclusion that: A. A tall flower stalk does not have a significant effect on either the attraction of pollinators or their survival rate when they visit a Sundew plant.
B. A tall flower stalk is equally important for attracting pollinators and preventing them from getting caught by the Sundew plant.
C. A tall flower stalk is more important for attracting pollinators than for preventing the sundew plants from accidentally catching pollinators.
D. A tall flower stalk is more important for preventing the sundew plants from accidentally catching pollinators than for attracting pollinators.
