-40° C, and in the summer it can be as high 20° C. There are two real seasons: a growing season and a dormant season. The growing season is when there is no frost and plants can grow (which lasts from 100 to 175 days). During the dormant (not growing) season nothing can grow because it's too cold. Taiga- Long, cold winters, and short, mild, wet summers are typical of this region. In the winter, chilly winds from the arctic cause bitterly cold weather in the taiga. The length of day also varies with the seasons in the taiga. Winter days are short, while summer days are long. The average temperature is below freezing for six months out of the year. The winter temperature range is -50 to -1° C The high in summer can be 20° C. The summers are mostly warm, rainy and humid. They are also very short with about 50 to 100 frost free days. The total precipitation in a year is 300 - 850 mm 4. Connect the climate diagram and biome.
The tundra is the world's coldest and driest biomes. The average annual temperature is -28° C. Nights can last for weeks when the sun barely rises during some months in the winter, and the temperature can drop to -70° C. During the summer the sun shines almost 24 hours a day. Summer are usually warm. Average summer temperatures range from 3° to 16°C. TaigaTaiga is the Russian word for forest and is the largest biome in the world. It stretches over Eurasia and North America. The taiga is located near the top of the world, just below the tundra biome. The winters in the taiga are very cold with only snowfall. The summers are warm, rainy, and humid. Some of the animals in the taiga hibernate in the winter, some fly south if they can, while some just cooperate with the environment. GrasslandsGrassland biomes can be found in the middle latitudes. They can have either moist continental climates or dry subtropical climates. There
Tundra Tundra is the world's youngest biome. It was formed 10 000 years ago. Located at latitudes 55° to 70° North. Almost all tundras are located in the Northern Hemisphere, encircling arctic desert and extending south to the coniferous forests of the taiga. The ecotone (ecological boundary region) between the tundra and the forest is known as the tree line or timberline. Tundra comes from the Finnish word tunturi, meaning treeless plain. It is noted for its frost-moulded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Dead organic material functions as a nutrient pool. The two major nutrients are nitrogen and phosphorus. Nitrogen is created by biological fixation, and phosphorus is created
experience rainforests firsthand. o Animal products - Rainforests provide numerous animal products including honey, game meat, hides and ivory. o Ecosystem services - Rainforests play an important role in maintaining biological diversity, modulating precipitation infiltration and flooding, increasing scientific knowledge and in the spiritual well-being of humans. Boreal forests Boreal forests are also known by name Taiga. The largest areas of boreal forest are located in Russia and Canada, but also in the extreme northern continental United States, in Eurasia (most of Sweden, Finland, inland Norway), northern Kazakhstan, northern Mongolia and northern Japan. These forests are occupying about 17% of the land and make up 27% of the world's forest cover. Temperature in these forests is usually low, as the canopy allows very low sunlight to penetrate.
25°C to 30°C with occasional extreme heat in some interior locations exceeding 40°C. Canada's land ranges from fertile agricultural plains in the south to freezing tundras in the north. The southwest of Canada has a mild climate. Cold winters characterize most of the rest of Canada. The magnetic North Pole is within Nunavut. There are five biomes in Canada: the Arctic Biome, the Tundra, the Taiga Biome, the Prairies and the Deciduous Forests. The Arctic biome is cold, windy and the land is permafrost. There are long periods of darkness and light. The growing season is very short. The tundra is located near the Arctic region. It is cold and windy as well. The land is permafrost and desertlike. The growing season is 5060 days and that is why there grow plants such as mosses and lichens. 6. Animals

Temperate deciduous forests, woodlands and shrub Tartu 2008 Location: Temperate forests are typical of all European continent, the Eastern region of Asia (in special, Chinese and Japan) and North America. Also are finded in tempered areas of South America. Climate: The average temperature in temperate forests is 50° F. Summers are mild, and average about 70° F, while winter temperatures are often well blow freezing. The average yearly precipitation is 30-60 inches. This precipitation falls throughout the year, but in the winter it falls as snow. There are four seasons in this biome, with warm summers and cold winters, often snowy. In autumn, the leaves change color and fall from the trees. The leaves decay on the forest floor, so the soil is very rich. Because of this, and because of the long growing season, many deciduous forests have been cut down for farming purposes. Plants: Trees of this biome include hardwoods such as maple, oak, hickory, and beech. There
