Answer:
In temperate grasslands, grasses and other plants must survive cold frozen winters and hot, dry summer droughts. Many grasses can live quite happily under a heavy layer of snow.
During a cold winter, grasses become dormant, which means that they don't grow new leaves, seeds or roots until spring comes with warmer temperatures and fresh rain. Many grasses are also specially adapted to handle heat and droughts without much water.
