Learn how a colony of leaf-cutter ants grows food and maintains the colony in the video from NATURE: Animal Homes. Millions of leaf-cutter ants travel throughout the forest, cutting leaves, and transporting them back to the colony. The ants use the leaves for farming fungus. The queen and several different types of worker ants all play a role in maintaining the colony. Because the ants behave more like a single animal than millions of individuals, many scientists consider a colony to be a super-organism.
