Introduction A forest is a complex ecosystem which is predominantly composed of trees‚ shrubs and is usually a closed canopy. Forests are storehouses of a large variety of life forms such as plants‚ mammals‚ birds‚ insects and reptiles etc. Also the forests have abundant microorganisms and fungi‚ which do the important work of decomposing dead organic matter thereby enriching the soil. Nearly 4billion hectares of forest cover the earth’s surface‚ roughly 30 percent of its total land area.The forest

analogy and a generalization because a couple degrees warmer in Europe or a temperate zone may not be that tragic‚ but what about the consequences of a few degrees temperate increase closer to the equator where the average temperate is consistently high? A few degrees warmer in Europe‚ or Minnesota might not be too tragic‚ but residents near the equator would undoubtedly disagree. A temperature increase on the Sahara desert‚ or anywhere along the equator would have definite tragic results. Next

TUNDRA The Tundra is the coldest of all the Biomes and being situated in the extreme north of the planet has desert like conditions. It has extremely low temperatures‚ poor nutrients‚ and short growing seasons. There is a very low precipitation of less than five inches a year which is coupled with strong‚ dry winds. There is a very large annual amount of snowfall in the region which surprisingly is advantageous to plant and animal life as the snow provides and insulation layer on the surface of
