Where Is Here?
Prairies are vast
grassland
ecosystems that
occupy
the Great
Plains
of North America.
The deep roots of grasses contribute to a fertile
soil
well suited for crops in the grass family such as wheat, barley, oats, rye and corn.
In the Great Lakes region, tall grasses grade into eastern deciduous forests in the Prairie-and-Oak Transition
Zone
