Dear Student,
Answer to your question is as follows :
The temperate grasslands of North America are known as the Prairies. It is a region of flat, gently sloping or hilly land.
For most part, prairies are treeless but, near the low lying plains, flanking river valleys, woodlands can be found.
Prairies are practically tree-less.
Where water is available, trees such as willows, alders and poplars grow.
Places that receive rainfall of over 50cm, are suitable for farming as the soil is fertile.
Though the major crop of this area is maize, other crops including potatoes, soyabean, cotton, and alfa-alfa is also grown.
Areas where rainfall is very little or unreliable, grasses are short and sparse.
These areas are suitable for cattle rearing.
