* A biome is a large
geographic area with
similar climate and
ecosystems
* Tundra
* Coniferous/Boreal Forest(Taiga)
* Deciduous Forest
* Tropical Rain Forest
* Grassland/Savannah
* Desert
•
Where is the tundra?
• Around the North Pole and near the Arctic Ocean
• Climate (weather)
• Very cold and dry
• Temperature: less than -5°C
• Only has 25 centimeters or less of rain every year
•
What the land looks like
• Permafrost: the dirt that is always frozen (even in the
spring and summer)
• Comes from Russian word meaning “treeless”
• Plants
• Fungi and algae
• They cover the rocks and ground
• Animals
caribou
duck
lemming
wolf
ermine
marmot
polar bear
sandy hill
crane
musk ox
snowy owl
• Climate
• Cold and snowy
• What the land looks like
• In the winter:
• Ground is frozen
• In the spring:
• Taiga: swampy forest
• Snow melts and the ground becomes wet and swampy
because the deeper ground is frozen
Alaska
Canada
Europe
Asia
In Canada, Alaska, northern Asia, and northern Europe
• Conifer trees (have cones)
cone
• Have needles covered with wax
• Wax protects the needles from freezing
needles
Kinds of conifer trees
pine

• Climate
• Summers are warm
• Winters are cold
• Gets 75 centimeters of rain every year
of rain!)
(that’s over 2 feet
• What is special about deciduous trees?
• The leaves change colors and fall off the trees in autumn and
grow new leaves in the spring
• The leaves on the ground make the dirt better and help plants
grow.
Deciduous forests are between northeastern United States and
Canada. Some are in the eastern United States. Others grow in
Europe and eastern Asia.

• Climate
• Rains almost everyday
• Gets almost 10 feet of
rain every year.
• Very hot all year long
Decatur
The largest tropical rainforest is in South America. It is called
the Amazon rain forest. They are also found in central Africa,
Central America, Southeast Asia, Hawaii, and a small area of
Australia.
• There are _____
two kinds of grasslands.
• Temperate grasslands: called prairies
• Tropical grasslands: called savannas
• Climate
• All grasslands get between 25 and 75 centimeters of rain every year.
Coniferous forest
The largest grassland is in Africa. There are also grasslands
in North America, South America, central Asia, and northern
Australia.
• Some are found in the United States
• Texas has the LBJ grasslands.
• Land is usually flat
• Not a lot of trees
grass
• The most important plant is __________.
• Largest savannas are found in Africa
• There are only a few trees on the savanna
• Why don’t a lot of trees grow?
• Savanna does not get a
lot of rain
• People set the grass
on fire to stop trees
from growing
• Animals eat the trees
before they can start
growing tall
• Grass
• Can live without a lot of rain
• Acacia tree
• Baobab tree

There are __________
kinds of deserts.
• Hot deserts and cold deserts
hot desert
cold desert

In Africa, western North America, western Asia, central Australia,
and western South America.
* Climate
* gets less than 25 centimeters of rain every year
* hot during the day and cool at night
* Climate
* gets less than 25 centimeters of rain every year
* cold all of the time

* Marine
* Freshwater
ocean
* The marine biome is the _________________
biome.
* covers about 70% of the Earth
* has salt water
* Organisms that live in the ocean are able to live in the salt water.
* sunlight, water pressure, and water movement affect the organisms
too
• because of these things, the ocean is divided into different
areas
• different organisms live in each area
* The water that is very deep has cold temperatures, high pressures, and is
very dark
• Many of the plants live near the top of the water
• they need the sunlight to help them grow and make food
• Most marine organisms live near the top of the water or close to land
• Many animals dig down into the sand or hang on to rocks, so they do not
get lost in the sea
• Other larger animals live where the water is deep

* Freshwater means it does not have _______________
in it
* Includes still water and moving water
* Examples of still water
* lakes and ponds
* Examples of moving water
* rivers and streams
* Many of the plants that live in freshwater have strong roots to
keep them in one place.
* Some plants grow around the edge of the lake or float on the top
of the water
