TUNDRA • The growing season ranges from 50 to 60 days. • The average winter temperature is -34° C (-30° F), but the average summer temperature is 3-12° C (37-54° F) which enables this biome to sustain life. • Yearly precipitation, including melting snow, is 15 to 25 cm (6 to 10 inches)
TAIGA • The taiga is the largest biome in the world. • It covers large parts of Canada, Europe, and Asia. • This forest is covered with coniferous trees. In fact, sometimes the taiga is called a coniferous forest. • In the taiga, summers are warm and rainy, and the winters are very cold. There is lots of snow in the forests, too. During the summer, it is usually around 70 degrees Fahrenheit. In the winter, the high temperature averages around 30 degrees Fahrenheit, whereas the low temperature is 65 degrees BELOW zero!
Lichens and mosses are important, but most of the plants are evergreen trees. There are many types of coniferous trees such as pine, spruce, hemlock, and fur. • The trees are narrow and grow very close together. This is so they can help protect each other from the weather. That snow and wind can be really cold!
GRASSLANDS • Grasslands receive about 10 to 30 inches of rain per year. If they received more rain, the grasslands would become a forest. If they received less, they would become a desert. Grasslands are often located between deserts and forests. • Grassland soil tends to be deep and fertile. • temperature range is very large over the course of the year. • Summer temperatures can be well over 38 degrees Celsius (100 degrees Fahrenheit), while winter temperatues can be as low as -40 degrees Celsius (-40 degrees Fahrenheit).
TEMPERATE DECIDUOUS FOREST • The Temperate Deciduous Forest biome has four seasons of winter, spring, summer, and fall. Animals and plants have special adaptations to cope with these yearly changes. • The word "deciduous" means exactly what the leaves on these trees do: change color in autumn, fall off in the winter, and grow back again in the spring. This adaptation helps trees in the forest survive winter. • In the winter, precipitation (rainfall) is in the form of sleet, snow, and hail. The average rainfall is 30 to 60 inches per year. • The average temperature of the forest is about 50 degrees Fahrenheit.
TROPICAL RAIN FOREST • The tropical rain forest is a forest of tall trees in a region of year-round warmth. • An average of 50 to 260 inches of rain falls yearly. • temperature in a rain forest rarely gets higher than 93 °F or drops below 68 °F • Trees are TALL to stretch above the canopy and leaves are HUGE and angled to funnel off rain and collect sun for photosynthesis. • Soil is very poor because of lack of decomposition • Has the highest biodiversity of all biomes
DESERT • The desert is often very hot in the daytime. At night, it may get somewhat chilly, or even cold. • Even the wettest deserts get less than 10 inches a year. • there may be only a few very large rains and they are usually very far apart. But when it rains, there may be quite a downpour! After the rain, desert flowers bloom. • Desert plants have adaptations : Ability to collect and store water and features that reduce water loss • Some animals rely on bird seeds for water (seeds can contain up to 50% water). • Many animals in the desert spend most of the day underground. These animals come out at night to eat and hunt. Creatures that come out at night are called nocturnal.
