Ants nest in leaf litter or wood. They eat plants, seeds, and decaying plants and animal materials. Some ants eat honeydew that are produced by aphids. Some ants even eat termites.
Ants become the food source of arthropods (spiders, beetles, ant lion), amphibians (wood frogs, red eft), birds (downy woodpecker), some carnivorous plants (pitcher plant), and mammals (bear, ant eater).
