When insects, bats, birds and other animals visit flowers to feed on the nectar and pollen, they usually pollinate the flowers in the process, so that both partners benefit from this mutualistic association. Secondary metabolites are involved primarily to provide either visual or olfactory attraction in terms of flower colour and flower scent. They may also be present in the nectar and pollen to interact with certain visitors.
