All the ecosystems of the world together form the biosphere. It consists of all the living organisms and all the regions of the earth and its atmosphere where they live. A Biome is a large unit characterised by flora and fauna found in a specific climatic zone. For e.g., a dese..

Also referred as 'tropical grasslands', primarily located in equatorial and sub - tropical regions of the globe (especially South America, Central Africa and Australia). The biome is characterized by warm climatic plains with coarse grass and margins are with scattered trees. Common trees..

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 (largest ecologic..

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 about 8 x 10 6 sq.km area (8 million km 2 ) extendi..

In the Earth's biosphere, water is essential to all forms of life. Interestingly, it is also the biospheres most abundant compound and a unique substance from the chemical point of view. About 75% of the Earth's surface consists of water. Water is present as either (a) Solid - i..

Policy decisions are already taken in India to undertake technology developments for alternatives to CFCs. Two CSIR laboratories - National chemical laboratory and Indian Institute of Chemical technology are working on this. Along with this, parameters for design modifications such as com..

Air is an important natural resource providing the basis of life on earth. Entire biosphere depends on air. Air in the atmosphere provides oxygen to plants and animals, by virtue of which they are able to live. The composition of air (78% N, 21% O, 0.03% CO 2 ) is necessary to b..
