Leaf-cutter ants harvest leaves and carry them to fungi that convert plant material into a usable form for the ants to digest. The fungi depend on the leaves for nutrients. The ants also produce an antibiotic on their bodies that helps protect the fungi from harmful bacteria. Which of these explains the relationship between the leaf-cutter ants and the fungi?

• Predation, because the ants feed on the fungi 

• Mutualism, because both the ants and the fungi benefit from each other 

• Competition, because both organisms consume the same resource for energy

• Commensalism, because the ants receive energy from the fungi and the fungi are unaffected
