Ants are important organisms in an ecosystem and their loss would have far reaching effects. Anything that feeds on ants would lose an important source of nutrition. Ants in turn, are herbivores, foragers and scavengers.Organisms that use ants for food include, birds, reptiles, amphibians. Ants are also important because they make up approximately 15-20% of terrestrial biomass. They live in colonies with a division of labor amongst the inhabitants. Ants have various symbiotic relationships with other organisms. One such relationship is silverfish and army ants. This commensal relationship allows the silverfish to feed on food that the ants don't use. Ants can also help with seed dispersal of certain plants. Some ants live in a mutual relationship with fungi, providing food for the fungi, while in turn, feeding on structures the fungi produce. People in various cultures also feed on species of ants. Should ants perish, the food webs that include ants, would be adversely affected.
