Which of the following best defines a pollinator?

A pollinator is defined as an organism that transports pollen from one flower to another, facilitating the process of fertilization in plants. This role is crucial for the reproductive cycle of many flowering plants, allowing them to produce seeds and fruit. Pollinators can include various species such as bees, butterflies, birds, bats, and certain insects.

This role is not only significant for the plants themselves but also for the wider ecosystem, including agriculture, where many crops rely on pollinators for successful production. The effectiveness of pollinators in transferring pollen can directly impact the yield and health of plant populations.

In contrast, creatures that consume pests are considered beneficial in pest management but do not play a role in the pollination process. Species that solely produce nectar contribute to the ecosystem but do not define the pollination function. A type of pesticide pertains to chemical agents used to control pests, which does not relate to the definition of a pollinator at all.
