Q. Consider the following ecosystems:
1. Taiga
2. Tropical evergreen
3. Tropical deciduous
4. Tundra
The correct sequence in decreasing order of the albedo values of these ecosystems is
Answer:
4, 1, 3, 2
Notes: The correct sequence in decreasing order of the albedo values of these ecosystems are Tundra, Taiga, Tropical deciduous and Tropical evergreen.
Taiga, generally referred to in North America as boreal forest or snow forest, is a biome characterized by coniferous forests consisting mostly of pines, spruces, and larches. The taiga or boreal forest is the world's largest land biome.
The tropical evergreen forests usually occur in areas receiving more than 200 cm of rainfall and having a temperature of 15 to 30 degrees Celsius. They occupy about seven per cent of the earth's land surface and habours more than half of the world's plants and animals.
Tropical deciduous forests occur in regions with heavy rainfall for part of the year followed by a marked dry season. These forest formations are dense and lush during the wet summers, but become a dry landscape during the dry winters when most trees shed their leaves.
Tundra is a type of biome where the tree growth is hindered by low temperatures and short growing seasons. The term tundra comes through Russian from the Kildin.
