Transcript Biome PowerPoint 2

Which Biome do you live in?
What is a Biome?
• An region characterized by the major
organisms that live there and its climate.
– Can you name one?
Where are they?
What are the Biomes?
•
•
•
•
•
•
•
Rainforest
Tundra
Taiga
Deciduous
Grassland
Desert
Ocean
• Can be Tropical or Temperate
• Tropical rainforest receives 80-400 inches
of rainfall/year. (High Rainfall)
• Most Diversity of Organisms
• Temperate rainforest receive about 100
inches/year

FUN FACTS!
To be a rainforest it must:
• Lie between the Tropic of Cancer and the
Tropic of Capricorn.
• Receive rainfall regularly throughout the
year (80-400 inches per year).
• Remain warm and frost free all year long
(mean temperatures are between 70° and
85°F) with very little daily fluctuation.

Covers a fifth of the earth's surface.
Located in the North Pole.
Permafrost – Permanently frozen layer of earth.
The average annual temperature is only 10 to 20F
Water is unavailable during most of the year.
Low rainfall, usually less than 10 inches
Plants in the tundra are small and grow close to
the ground.
• Lichens grow in this area on exposed rock.
This plant grows in the
tundra…Why the red leaves?
Common Animals in the Tundra
Artic Fox
Tundra Swan
Caribou
Musk Ox
Polar Bear
Snow Bunting
Snow Owl
Rock Ptarmigan
• Canada, Europe and Asia
• Evergreen/Coniferous trees
• Very Cold Winters, but Warm summers as
well.
• Moderate rainfall (12-22 inches mostly in
the summer)
• Long nights in the winter and long days in
the summer.
Common Taiga Organisms
•
•
•
•
•
•
•
•
•
Pine trees
Fir trees
Aspen trees
Hawk Owl
Lynx
Beaver
Moose
Snowshoe Rabbit
TONS OF INSECTS!!
• North Africa, U.S., Antarctica, Australia
• Extremes: VERY Dry, VERY Hot, VERY Cold
• Deserts come in hot or cold variety VERY Hot
over 100 degrees during the day
• Nights in the 40’s
• VERY little rain(less than 10 inches a year)*
(Until rainy season and then flooding can occur).
• Why does the weather fluctuate like this in the
desert but not here?
– Lack of humidity to trap heat.
Common Desert organisms

• United States, Canada, Europe, parts of
Russia, China, and Japan.
• Has four seasons: Winter, fall, spring, and
summer
• Heavy rain fall 30-60 inches a year.
• Moderate warm summers and cold winters
• What causes seasons?

U.S. and Canada
Very few trees except near rivers
Moderate to low rainfall 10 to 30 inches.
Very fertile soil lots of seeds.
Farm land located in these areas
Cattle, Bison,and Prong Horn graze these fields.
Temperate and Tropical Grasslands
– Tropical –Near the equator warm all year
– Temperate – Have hot summers and harsh winters
