Researches indicate that the acacia trees without the ants as guests suffer more from attacks and harms by the insects, compared with those trees hosting the ants. In a research, the savage plants spurting out from the trunk of the acacia tree, were completely chew and crushed by the ants till they were completely destroyed. Moreover, the ants attacked the branches and leaves of the other plants that had contact with the shady spot of the acacia tree. The entire ant community was very much active in patrolling and cleaning the plant. Since none of the both sides could neither make such decision on their own and act accordingly, nor provide such conditions with their own will, it is evident that Allah who created both parties established this complicated and intricate balance.
Some plants have deep hollows called domatia in the biologocial terminology.
Domatia has no function other than constituting a shelter for the ant colonies. Domatias have thin layers of covers made up of tissues that enable the ants to go in and out freely. These covers hide the divisions that contain the special food produced by the plant for the ants. Again, the plant has no benefit of this food, yet produces it only for the advantage of the ants. It may be concluded that domatia is a special structure for the survival of the ants.
