Parque Nacional Marino Ballena
Leaf-cutting ants harvest around 15% of all the green matter produced by the rain forest. All of that foliage is broken down and recycled back into the web of forest life.
The ants consume some of the plant juices, but the bulk of the leaves are fed to a fungus, which provides the primary source of nutrients for the colony. DNA testing has determined that the fungus the ants grow today is genetically identical to the one their ancestors learned to cultivate 50 million years ago.
