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.
