Question

The Tundra type of climate only supports growth of _ _ __ _ _ _.
A. Mosses
B. Lichens
C. Both a and b
D. Maple trees

Answer 1

Hint: The biodiversity of the Tundra is low: 1,700 species of flora can be found and there are only 48 land mammals, while thousands of insects and birds migrate to the marshes every year. Few species with large populations exist.

Complete Answer:
- There are three regions and associated types of tundra: Arctic tundra, Alpine Tundra, and Antarctic tundra. The main vegetation of both of these groups is grasses, mosses, and lichens. In some of the tundra, trees grow.
- Dwarf shrubs, sedges, and grasses, mosses, and lichens are composed of tundra vegetation. In some tundra regions, scattered trees grow. The ecotone (or ecological boundary region) is referred to as the tree line or timberline between the tundra and the forest. Nitrogen and phosphorus are rich in the tundra soil.
- The ecotone (or ecological boundary region) is known as the tree-line or timberline between the tundra and the forest. The term "tundra" commonly applies only to the areas where permafrost or permanently frozen soil is the subsoil. The Arctic tundra is a vast region with a strong landscape that has been frozen for much of the year.

The right answer is option C (Both a and b).

Note: From 25-90 cm (9.8-35.4 inches) down, the soil there is frozen, and it is difficult for trees to grow. Instead, only low-growing plants like moss, heath, and lichen can support bare and sometimes rocky ground. In the polar Tundra regions, there are two primary seasons, winter and summer.
