Reаd the fоllоwing descriptiоn of а relаtionship between two species and choose the type of relationship it is. The bullhorn acacia tree produces thorns that acacia ants can use for shelter. The bullhorn acacia will fare poorly without the acacia ants, because the ants prevent other organisms from eating the acacia. Acacia ants can form relationships with up to four different species of acacia trees, which means that acacia ants do not need the bullhorn acacia specifically to survive but can survive on other species of acacia.
