TUNDRA BIOME
The tundra is near the North Pole.
Trees do not grow there.
Winters are very cold.
Summers last for a very short time.
It is frozen and never melts.

TUNDRA ANIMALS
Arctic Fox
(omnivore)
Caribou
(herbivore)
Harlequin Duck
(main diet is small sea
creatures; arctic fox is its
main predator)
Musk Ox
(herbivore; predators are
arctic wolf and polar bear)
Snowy Owl
(carnivore; preys are arctic fox
and small animals)Polar Bear
CONIFEROUS FOREST BIOME
Summers are short and mild and the winters
are long, cold and dry.
Plants are mostly evergreen conifers with
leaves like needles, such as pine, fir and
spruce.
Soil is thin and lacking in nutrients.
CONIFEROUS FOREST LOCATION
Located mainly between the 45th and 57th North latitudes – south of the tundra & north of temperate grasslands & temperate deciduous forest
Found in Eurasia, North America, Siberia, Scandinavia, Alaska, and Canada
CONIFEROUS FOREST ANIMALS
Gray
Wolf
Black
Bear
(omnivore
)
Bald Eagle
Northern Lynx
(eats small
mammals)
Bobcat
(eats small mammals)
Wolverine
(eats small mammals)
CONIFEROUS FOREST PLANTS
Balsam Fir
(squirrels, deer, caribous
eat its buds)
Eastern Red Cedar
(animals such as birds
eat its berry fruit)
Siberian Spruce
(pine cones for
small mammals)
Jack Pine
(pine cones
for rodents)
White Fir
(seeds for
squirrels)
DECIDUOUS FOREST BIOME
The leaves change color before they fall.
Deciduous trees lose their leaves in autumn.
The fallen leaves are good for the soil.
In spring, new leaves grow and the forest is
green again.
The leaves are wide to catch more sunshine.
DECIDUOUS FOREST LOCATIONS
• Found in eastern North America, northeastern Asia, and western and central
Europe (lower middle latitudes in the Northern hemisphere)
• Mainly located in middle latitudes of northern hemisphere (30°-60°N)
DECIDUOUS FOREST ANIMALS
White-Tailed Deer
Least Weasel
(eats rodents, birds,
poultry, and rabbits)
European Red SquirrelEastern Chipmunk
(omnivore)
Duckbill Platypus
(carnivore)
Coyote
(omnivore)
Fat Dormouse
(eats fruits, seeds,
insects, and bird eggs)
DECIDUOUS FOREST PLANTS
Tawny Milksap
Mushroom
Lady Fern
Guelder Rose
Carpet Moss
White Birch Tree
Pecan Tree
DESERT BIOME
A desert can be very hot in daytime and cold at
night (no rainfall at all.)
Some deserts are cold all the time.
Desert plants need special ways of getting water;
their leaves and roots are special.
Desert animals have special ways to survive.
Many shelter underground. Some animals are
active at night when it’s cool.
DESERT LOCATIONS
•Major hot and dry deserts are located between 25 and 40
degrees North and South latitude in the interiors of continents
•Four major deserts of North America include the Chihuahuan,
Sonoran, Mojave, and Great Basin
DESERT ANIMALS
Roadrunner

Thorny Devil Lizard
(eats ants; a prey
of birds)

animals)

GRASSLAND BIOME
Grasses are the main kind of plant in grasslands.
There are not many trees in grasslands.
Some grasslands are hot all year round. Some
grassland areas have hot summers and very cold
winters.
Grasslands are big open areas that get between
25 and 75 cm of rain per year. This is less rain
than a forest gets and more than a desert gets.
GRASSLAND LOCATIONS
Temperate grasslands located in central North America (prairies – have tall
grasses), Europe and Asia (steppes – short grasses), and South America
(Pampas).

SAVANNA BIOME
A tropical grassland with some clumps of trees.
It is characterized by its specific wet (summer)
and dry (long winter) seasons.
Contain the greatest number of grazing animals
on Earth.
Fire plays a large role in this ecosystem.
Rainy and Dry Season.

(carnivore; eats mainly
deer and antelopes)
Zebra
Emu (eat plants

Baboon
(eat plants, fruits,
and bugs)

(eats mainly small
animals, but it also eats
fruits)

RAIN FOREST BIOME
Rainforests are thick, warm and wet forests.
They are forests that get at least 250 cm a year of
rain, often more.
It has a lot of rain (high rainfall throughout the
year.)
Tropical forests are located near the equator.
Areas that are warm and frost-free.
TROPICAL RAIN FOREST
•Located near equator (between tropic of cancer & tropic of capricorn)
•Found in Central and South America, southeast Asia,
West Africa and the islands.
