The leafcutter ant is a species of tropical ant that will cut pieces of leaves from trees and carry them back to their nest. The ants will chew up these leaves into a pulp and use the pulp to grow a type of fungus. Like a farmer, the ants harvest the fungus as a crop to feed the colony while the fungus grows and feeds on the pulp provided by the ants. Which type of interaction best describes the fungus and the ants? commensalism
