Tropical leafcutter ants can chomp as much as 20 percent of the foliage from trees in rainforests. The ants first tear the leaves into tiny bits and then haul them back to their fungus-covered homes. While they don’t actually eat the leaves, they use the leaf matter to enrich the dens where they cultivate fungus for food. Ants, you could say, are the original organic gardeners!
