Option 1 : Large grasslands
The correct answer is Large grasslands.
- Grasslands (steppes) are temperate environments, with warm to hot summers and cool to very cold winters; temperatures are often extreme in these midcontinental areas.
- They are often located between temperate forests and deserts, and annual precipitation falls between the amounts characteristic of those zones.
- Grassland is largely dominated by grasses, but with annual and perennial forbs intermixed in different proportions in different areas.
- The average height of the grass is correlated with rainfall, so there are tall-, medium-, and short-grass prairie zones across a longitudinal gradient from east to west in North America.
- The aspect changes considerably between spring when the grasses are green and the forbs are in bloom and midsummer when brown, seeding and dying plants predominate.
- Some steppes, especially in more arid areas, are dominated by shrubs (they are designated as shrub-steppes) and differ from deserts primarily in their higher latitudes, lower mean temperatures, and lower diversity.
Hence, Large grassland vegetation is found in steppe-type climatic regions.
