How Plants Attract Bodyguards

Plants use nectar to attract pollinators and bodyguards, forming mutualistic relationships. Some plants have extra floral nectaries to attract animals for protection. Inga plants use ants to fend off insects, while passion flowers use ants and chemicals for defense. Cotton plants attract parasitic wasps to control caterpillars. Nectar also contains compounds that protect against viruses, bacteria, and fungi, though it requires energy to produce.
