Question

How does a cardinal help increase the size of the sunflower population in its ecosystem

Answer 1

Answer:-

Cross pollination takes place when sunflower seeds are dropped by the birds. The birds are an important factor for pollination. They are known to be pollinators. When birds eat fruits or any other fruit containing seeds they acts as pollinator as they carry the seeds and drop them wherever they go thus spreading the seeds everywhere.

They fertilize the plant in the same way as a pollinator does by transferring pollen. Plant attracts birds with their beautiful colours and nuts as a source of food. The seeds pass through the bird’s digestive system, at times birds drop seeds from their mouth thus helping in seed dispersal.

Answer 2

By helping them in cross pollination through dropping the sunflower seeds.

The birds are very factor for pollination as they act as pollinators. Cardinals are the pollinator that eat fruits, raspberry and other fruit containing seeds.

The flower of these plants attracts the birds and they feed on the fruits and spread the seeds wherever they go. This helps in pollination.
