Detailed explanation-1: -Temperate grasslands have cold winters and warm summers with some rain. The grasses die back to their roots annually and the soil and the sod protect the roots and the new buds from the cold of winter or dry conditions. A few trees may be found in this biome along the streams, but not many due to the lack of rainfall.

Detailed explanation-2: -Prairies are enormous stretches of flat grassland with moderate temperatures, moderate rainfall, and few trees. When people talk about the prairie, they are usually referring to the golden, wheat-covered land in the middle of North America.

Detailed explanation-3: -Prairies are ecosystems considered part of the temperate grasslands, savannas, and shrublands biome by ecologists, based on similar temperate climates, moderate rainfall, and a composition of grasses, herbs, and shrubs, rather than trees, as the dominant vegetation type.

Detailed explanation-4: -The temperate grasslands of North America are known as the Prairies (Fig. 9.1). It is a region of flat, gently sloping or hilly land. For the most part, prairies are treeless but, near the low lying plains, flanking river valleys, woodlands can be found.
