Tropical leafcutter ants collect leaf cuttings which they transport to special underground chambers. There, they chew the leaves to create nursery beds on which they grow a species of fungus they use for food
When ant queens disperse to establish new colonies, they carry
the fungus with them, dispersing it as well (this benefits the fungus). In the ants' nest, the
fungus is at risk of being destroyed by another fungal species that is able to grow in the same
habitat, using the same limited resources. On their bodies, the ants carry and provide a
home for bacteria that produce antibiotics the ants use to kill this second fungus and thereby
protect their food supply. In this system, the relationship between the leafcutter ants and their
fungal food species is:
A. interspecific competition.
B. mutualism.
C. predation.
D. parasitism.
E. commensalism.
