Posted by on .

this is the question my answer is below can someone make suggestions or help me edit it thanks - i read everythig i could find on this and not sure if my answer makes sense.

Hummingbirds need to feed several times an hour. Flowers that attract hummingbirds typically contain a lot of nectar. This keeps the hummingbird at each flower longer before it moves on to another source. Flowers that attract nectar-feeding bees typically contain smaller amounts of nectar, and therefore a bee has to visit several flowers to obtain enough nectar. Explain how both adaptations lead to better chances of successful pollination."

my answer below not sure i got it right exactly

Hummingbirds are bigger than bees, so they need more energy (plant sugar). Moreover, it is known that hummingbirds use a lot of energy in flight and are often times very close to starvation between meals. As a result, Hummingbirds need to feed at high energy source locations such as flowers with lots of nectar, as flying around to different sources and just consuming small amounts of sugar might lead to starvation. WITH RESPECT TO POLLUNATION, if they don't have enough energy to fly and transfer the pollen to a receiving plant of the same species, then they won't reach that plant, and the pollen will go to waste with respect to reproduction ( the pollen may still be used as food ). So if the the receiving plant is, say, 50 miles away, the Hummingbird needs to have enough energy to fly that distance to transfer the pollen, and therefore that is why it eats only flowers with lots of nectar.

Bees on the other hand don't need as much energy, so they don't need to feed on plants with large amounts of nectar. They have enough energy to fly around and transfer the nectar by just feeding on small flowers. Since the bird feeds on multiple flowers, it gets a greater variety of pollen (presuming the flowers are of different species or even the same species but not clones) so it has a greater chance of transferring the to a correct species receipient since there are more choices (since it has pollen from multiple species) or at least a greater chance of increasing genetic diversity if the pollen is from the species but not a clone.

  • biology edit please - ,

    Frankly, your entire answer is nonsense, and misses the mark.

    Here are some questions to think on...the answers to these answer the question you are asked.

    1) How is pollen transfered to the pistil by the hummingbird? Could it be air from the wingflap? Does that require a longer visit to the flower?
    2) Bees are hairy creatures. How do they transfer pollen to the pistil?
    Would that have anything to do with them going to several flowers?

    You need to focus on the question asked, if you had done that, you wouldn't have given such nonsense as in the first paragraph. You can do better than that.
