An individual living thing.
Organism
Same type of organisms
living together in an area.
Population
Several different populations
living together and interacting
with each other.

components.

THE END!!
A BIOME is large region
characterized by a specific type of
climate and the plants and
animals that live there.
Tropical Rainforest

The BIOSPHERE is all the
biomes of the world including
the abiotic components.

Trophic level is
the position
organisms have
in the food
chain.
A FOOD CHAIN is
the transfer of
energy from one
organism to another
in an ecosystem in a
line.
A FOOD WEB is a
complex network
of interconnected
food chains in an
ecosystem.

Sunlight is the main energy source in an
ecosystem.
Percipitation is rain, sleet, hail, snow,
etc.
Soils contains the

things.

YEARLY AVERAGE TEMPERATURE & PRECIPITATION
Tundra is the coldest of all the biomes.
Tundra comes from the Finnish word
tunturia, meaning treeless plain.
When water saturates the upper surface,
bogs and ponds may form, providing
moisture for plants.
Soil in the Tundra is
poor in nutrients.
Permafrost is a layer of
soil that is frozen year
round. Only the top
active layer thaws out in
summer.

There are about 1,700 kinds of
plants in the arctic tundra.
Arctic Poppy
Arctic Dwarf Willows
Cotton grass/ sedge
There are two
types of TUNDRA:
Arctic Tundra
Alpine Tundra
ARCTIC TUNDRA
ALPINE TUNDRA
rctic tundra is in the northern hemisphere surrounding the north pole.
ainfall and snow combined average is 6 to 10 inches yearly.
oldest and driest of all the biomes.
he only trees that grow in the tundra are the dwarf willows.
ce melts during summer but can’t drain into the soil because it is frozen
overs 20% of the Earth’s surface.
he top layer of soil is called the active layer which melts during summer
nder the active layer is the permafrost which is frozen soil year round.
ame“tundra”is from the Finnish word tunturia, meaning treeless plain.
warf willow trees are only 4 inches tall.
eferred to as a cold desert.
verage winter temperature is –300 F and summer temp. is 37-540 F.

The frigid cold and deep snow makes life in the tundra very difficult.
Every animal must adapt in order to survive. Some have grown thick fur which
turns white in the winter. Others find a place to hibernate during the winter
months.
The arctic tundra is at the top of the world -- around the North Pole.
Animals are adapted to handle cold winters and to breed and raise
young quickly in the very short and cool summers.
Temperatures during the arctic winter can dip to -60 F (-51 C)! The
average temperature of the warmest month is between 50 F (10 C)
and 32 F (0 C). Sometimes as few as 55 days per year have a mean
temperature higher than 32 F (0 C). The average annual temperature
is only 10 to 20F (-12C to -6C).
The soil is often frozen. Permafrost, or permanent ice, usually exists
within a meter of the surface. Water is unavailable during most of the
year.
Annual precipitation is very low, usually less than 10 inches (25
centimeters)
