Mutualism refers to interactions between species that result in reciprocal benefits. There are several mutualistic interactions between plants and animals. These mutualisms are in the form of a biological barter in which the resources of one species are exchanged with the services of the other. Mutual interactions are common between plants and ants (Beattie, 1985; Rico-Gray and Oliveira, 2007). Myrmecophily, particularly in species of Acacia, is one such mutualism in which plants possess structural adaptations that provide ants with food and/or shelter. In exchange, ants protect plants from herbivores. Ants also act as seed dispersal agents. Many plant species produce fruits or seeds with special ant attractants – arils or elaiosomes. Ants carry such fruits and seeds to their nest. After consuming the attractants, the seeds/fruits are discarded with other wastes either in the nest or outside the nest entrance.
