Ants - Ants And The Ecosystem

species press vegetation food

Earth-dwelling species of ants turn and enrich more soil than do earthworms; predatory species of ants control insect pests and spider populations, as well as animal litter by devouring rotting carcasses. Other species of ants spread seeds, thereby propagating valuable vegetation. Ants can also be serious pests; for example, leaf-cutter ants, which grow fungi gardens for food, also strip massive amounts of leaves and flowers. They haul the vegetation to their nests and pulverize it into a paste, which they feed to fungi that grows like mold on bread. Ant colonies are enormous: one nest of the Brazilian ant Atta sexdens housed about 8 million ants. A colony this size can strip as much vegetation as a cow in just one day, causing serious agricultural destruction.
