arctic tundra biome

The Tundra Biome (Rus:Tundra - Arctic hill) - The word 'tundra' means 'North of the timber line'. Tundra biomes lie north of timberline or 60 o N latitude between the Arctic ocean and the Coniferous forests. It covers a..

The word 'tundra' means 'North of the timber line'. Tundra biomes lie north of timberline or 60 o N latitude between the Arctic ocean and the Coniferous forests. It covers about 8 x 10 6 sq.km area (8 million km 2 ) extending across North America, Eur..

Mainly on the basis of latitude and amount and periodicity of rainfall, terrestrial biomes are classified into several types - tundra, taiga, deciduous forests, tropical rain forests, chapparal, savannah, grassland and deser..

Variations in climatic conditions are observed not only in places on different latitudes but also with altitude. The various types of biomes can also be noted with varying altitudes as seen in the slopes of high Himalayan mountains in Asia, Andes in South America and the Rockies in North ..

Taiga are the 'northern coniferous forests' which are also referred as 'North Woods', very common in Siberia. Taiga extends as an east - west band across North America, Europe and Asia, just to the south of tundra (between 45 o N to 75 o N latitudes). In southern hemisphere it is found in..

Mainly on the basis of latitude and amount and periodicity of rainfall, terrestrial biomes are classified into several types - tundra, taiga, deciduous forests, tropical rain forests, chapparal, savannah, grassland and desert. These biomes are also referred as 'latitud..

Major Ecosystems (Biomes) - Biome is a large, regional or sub continental biosystem characterized by a major vegetation type or other distinct landscape characters such as tropical deciduous forest, tundra biome, etc. "The major terrestrial ecosystems (larges..

Vegetation in tundra is very sparse. Hence, it is also called 'arctic desert'. It exhibits very low species diversity. a) Biome is virtually treeless and is comprised of only Lichens (Cladonia - Reindeer moss) and Mosses (Sphagnum - Peat moss) forming the main vegetati..

Light affects the distribution of animals by affecting the vegetation. For example Tundra biome is characterized by insufficient light, low temperature, less vegetation so less animal life. While tropical area is characterized by high rainfall, strong light, sufficient vegetati..

The biotic and abiotic components form an interacting system called 'ecosystem'. Producers, consumers and decomposers are the various trophic levels, which are linked by their food relationship forming a 'food chain'. Several food chains are interrelated and interconnected to form a network called ..
