An ecosystem is a community of plants and animals whose lives are closely linked to each other and to the climate and soil of the area in which they grow and live. Ecosystems may be changed by human activity.

Rainforests are unique areas where strange animals survive in the warm, wet climate. Colder areas that receive enough rain will see temperate forests form. If there isn't enough rainfall, grasslands will fill the region.
Dry, hot regions will become desert, and cold regions of northern North America and Asia are called tundra. Taiga is the named given to land in between the cold tundra and the warmer temperate forest and grassland biomes.
Tundra is one of the coldest biome. Tundra means in Finnish - tunturia, meaning treeless plain. It is noted for its frost-molded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Tundra is separated into two types: arctic tundra and alpine tundra.
Coniferous forests are normally made up of cone-bearing or coniferous trees, such as hemlocks, pines, spruces and firs. The leaves of these trees are mainly small and needle-like or scale-like and most stay green all year around. All are softwoods able to survive cold temperature. They cover areas of North America from the Pacific to the Atlantic, and range across northern Europe, Scandinavia, Russia and across Asia through Siberia and Mongolia to northern China and northern Japan. Coniferous forests are found mainly in the northern hemisphere, although some are found in the southern hemisphere. The northern coniferous forests are called taiga or boreal forests.
Deciduous forests are usually found in the eastern part of North America, and the middle of Europe. Some of the major areas that they are in are southwest Russia, Japan, and eastern China. There are deciduous forests located in New Zealand, and southeastern Australia also. The Deciduous forest normally dont have much plants but there are many trees that contain big amounts of flowers. Animals need these trees because thats where they live and get food from. The trees have thick barks to protect them selves and keep animals out. Temperature there is from -30C to 30C, yearly average is 10°C, hot summers, cold winters. Precipitation is 750 to 1,500 mm of rain per year.
The Mediterranean is woods/shrub land biome which is found from areas with just over 100mm of rain per year to around 20 mm of rain per year; average annual temperatures range from beneath zero to about 20° In general, this biome is found cluster around the 30° north or south latitude line. These are the...
