The prairie is the name given to the grassland biomes of North America. On other continents the name may be different, savannah or pampas, but in all cases this is a habitat dominated by grasses. The grasses of the prairie can survive in areas where precipitation is less than that required in the forest biomes and they often have distinct wet and dry seasons. Fire is a very important element in the praire system. Most of the growth in these grasslands occurs in the root systems below ground. While it might seem that fire would destroy the prairie, it is the fire that will help to recycle nutrients back into the soil to be reused and the grasses regrow.
The below ground growth that happens with prairie grasses also benefits the grazers that make the grassland their home. Since the main growing part of the plant is below the ground, it has the ability to grow back even if most of the plant has been eaten. In fact, God designed these ecosystems to contain grazers with a preference for different parts of the grasses that grow here. Some grazers eat just the tops, while others prefer the middle or lower portions. This allows prairies to support a great variety and quantity of grazing animals.
