Scientists estimate that there are more than 20,000 species of ants. The species range in size from 1 mm long to 38 mm long and live in most
environments. The diets of ants range from flowers and seeds to fluids from
their own larvae. Ants have been able to successfully inhabit so many different
environments because their populations have been able to -
O adapt to a variety of habitats and food sources
O hybridize with other species of insects
O fill niches usually occupied by mammals
O occupy habitats that have no other life-forms
