The insects, butterflies, honeybees, and birds help flowering plants in Pollination.
Pollination is the transfer of pollen grains from the anther to stigma. It can be done in two ways either manually or naturally. When the pollen grains are transferred from one flower to another flower with the help of people can be referred to as manual pollination. In natural pollination, the pollination is done without the help of people, here the insects, butterflies, honeybees, and birds help to transfer pollen grains from one flower to another flower, and thus results in flowering or fertilization.
