Bumble bee buzz pollinating rose. This is an example of a plant-pollinator interaction. In the audio recording you can hear the bee switching between its low flight buzz as it moves between fliers to a high pitched buzz when standing on the flower. This high pitched buzz stimulates the flower to release pollen from the anthers. The bee then spreads that pollen to other rose flowers it visits and picks up more pollen to take back to its colony to help feed developing larvae.
