The average rainfall ranges from about 12 to 20 inches but permafrost (frozen soil) keeps this water near the surface and the soil is poorly drained.
The structure of a boreal forest is often only a tree layer and a ground layer (Figure 7). Thus, no photosynthesis occurs in the deciduous trees during the dormant winter period. Savannas are hot, tropical areas with temperatures averaging from 24 °C to 29 °C (75 °F to 84 °F) and an annual rainfall of 10–40 cm (3.9–15.7 in). In some cases, the annual rainfall can be as low as 2 cm (0.8 in) in subtropical deserts located in central Australia (“the Outback”) and northern Africa.Fires, mainly caused by lightning, are a natural disturbance in temperate grasslands. The ashes left behind after a fire are rich in nutrients like nitrogen that fertilize the soil and promote plant regrowth.Because of the moderate annual rainfall and temperatures, deciduous trees are the dominant plant in this biome (Figure 6).

These are evergreen coniferous trees like pines, spruce, and fir, which retain their needle-shaped leaves year-round.
C. taiga. Permafrost is any soil or rock that has been frozen beneath the ground for at least two consecutive years. This layer is called the active layer.
A. Tundra B.
And, as in the boreal forests, there is little evaporation due to the cold temperatures.Subtropical deserts exist between 15 ° and 30 ° north and south latitude and are centered on the Tropics of Cancer and Capricorn (Figure 3). The roots and rhizomes act to anchor plants into the ground and replenish the organic material (humus) in the soil when they die and decay.Temperate grasslands are found throughout central North America, where they are also known as prairies; they are also in Eurasia, where they are known as steppes (Figure 5).

Permafrost is characteristic of the _____. 0 0 0. This benefits evergreen trees, which grow faster than deciduous trees in the boreal forest. Favorite Answer. The annual rainfall in this biome ranges from 65 cm to 75 cm (25.6–29.5 in), and the majority of the rain falls in the winter. Often, the restoration or management of temperate grasslands requires the use of controlled burns to suppress the growth of trees and maintain the grasses.Which of the following statements about biomes is false?The chaparral is also called the scrub forest and is found in California, along the Mediterranean Sea, and along the southern coast of Australia (Figure 4). What is permafrost? Little moisture (<25 cm); covers nearly 30% of the Earth’s surface; wide daily and seasonal temperature fluctuations with soils that are easily disturbed by human activities, and slow to recover describes which biome? Arctic Tundra. Boreal forests lack the pronounced elements of the layered forest structure seen in tropical wet forests.
Precipitation is relatively constant throughout the year and ranges between 75 cm and 150 cm (29.5–59 in).The Arctic tundra lies north of the subarctic boreal forest and is located throughout the Arctic regions of the northern hemisphere (Figure 8).
