1. These are coniferous forests. 2. Pine, fur, cedar and spruce are the prevalent trees. 3. In some areas, trees are so dense that little light reaches the floor. 4. This biome is good habitat for elks, deer, geese, rabbits, pumas, lynx and many insects. |
1. Tundra consists of plains characterised by snow and ice. 2. There is poor light and extremely low temperature. Snowfall is scanty. 3. Vegetation is so sparse that it is also called the arctic desert. 4. This biome is virtually treeless. |
Aquatic Ecosystem : There are many kinds of aquatic ecosystems that differ widely with regard to abiotic factors. The aquatic ecosystems range from open ocean to small temporary puddles, have conditions of salinity, depth and fluctuations of temperature.
Fresh water environment : Lakes and ponds are stagnant fresh water bodies and occur particularly in every biome. They vary in size from less than a hectare to hundreds of hectares. The relatively shallow lakes called eutrophic lakes, have a rich accumulation of organic products. The fresh water ponds are called autotrophs and have microscopic phytoplanktons.
Streams and rivers differ in volume, temperature etc. The nature and composition of flora and fauna depend on the source of river and the land environment.
