What "pollinator" means in gardening

A pollinator is an animal (usually insects, birds, bats or other animals) that helps to transfer pollen from the male part of a flower to the female part of another flower of the same species, which is necessary for fertilization and the production of fruits and seeds. Pollinators are essential for many plants to reproduce and thrive, and play a crucial role in maintaining healthy ecosystems and providing food for both humans and wildlife.
