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.

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

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.
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.
verage winter temperature is –300 F and summer temp. is 37-540 F.
overs 20% of the Earth’s surface.
eferred to as a cold desert.

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)
