Pollination is only done by pollinators.  

The correct answer is 'False'.

Without bees, plants can begin to self-pollinate. Self-pollination refers to a flower that has the ability to pollinate itself and other flowers produced by the same plant, which over time reduces the genetic variability in the plant population.
Pollinators are those which cause pollen transfer from anther to stigma from plant. they can be biotic or abiotic agents such as , wind , water, insects , animals .
