Question

3. Why prairies are almost without trees?​

Answer 1

Prairies are practically tree-less. Where water is available, trees such as willows, alders and poplars grow. Places that receive rainfall of over 50 cm, are suitable for farming as the soil is fertile. ... Areas where rainfall is very little or unreliable, grasses are short and sparse....

Answer 2

Answer:

Each different species of grass grows best in a particular grassland environment ( determined by temperature, rainfall, and soil conditions). The seasonal drought, occasional fires, and grazing by large mammals all prevent woody shrubs and trees from invading and becoming established.
