What do you think of when you think of polar bears? You
probably imagine them in a snow-covered setting. Why don’t
polar bears live in the desert?
Biome –
a large area characterized by its climate and
the plants and animals that live in the area.
Ecosystems
Biomes
Only refers to a
VERY LARGE AREA
Can refer to a
small area to a
very large area
However, BOTH biomes and ecosystems have biotic and abiotic factors!
Land Biomes
1. Temperate Deciduous Forest
2. Coniferous Forest
3. Tropical Rain Forests
4. Temperate Grassland
5. Savannas
6. Deserts
7. Tundra
Forest Biomesfound in areas that have mild temperature and
plenty of rain
Three types of Forest Biome
1.Deciduous forest
2.Coniferous forest
3.Tropical Rainforest
Temperate Deciduous Forests
Animals that live in
Temperate Deciduous
Forests are bears,
snakes, woodpeckers.
Deciduous means “to fall off”
Leaves change color, leaves fall off
Deciduous trees shed their leaves to save water
during the winter or during the dry season.
Climate
Average Yearly Rainfall
29.5 to 49 inches
Average Temperature:
Summer: 82 F
Winter: 43F
Coniferous Forests
Conifers produce seeds in cones. They have special leaves that are shaped like needles.
The leaves have a thick, waxy coating.
Evergreen trees – trees that stay green all year long and do not lose all of their leaves
Average Yearly Rainfall:
14 to 29.5 inches
Average Temperature:
Summer: 57 F
Winter 14 F
Animals that live in Coniferous Forests
are: squirrels, insects, deer, moose,
porcupines
Tropical Rain Forests
Have more kinds of plants and animals than any other
land biome. Some animals live on the ground but most
live in the canopy or treetops.
Soil is thin and poor so roots of trees are above-ground
and vines grow up the tree trunks to reach the light.
Animals that live in
Tropical Rain Forests are birds
(over 1,400 species ),
butterflies, monkeys
Climate
Average Yearly Rainfall
Up to 157.5 inches
Average Temperature:
Summer: 93 F
Winter: 68F
Temperate Grasslands
Include grasses and other flowering plants, have few trees
Fires, drought, and grazing prevent the growth of trees and
shrubs.
Animals that live in
Temperature Grasslands are: prairie
dogs, mice, bison
Climate
Average Yearly Rainfall
10 to 29.5 inches
Average Temperature:
Summer: 86 F
Winter: 32F
Savannas
A grassland that has scattered clumps of trees and seasonal rain
Found in Africa, India, and South America
Climate
Average Yearly Rainfall
59 inches
Animals that live in
Savannas are:
Zebras, elephants, giraffes
and wildebeests.
Average Temperature:
Dry Season: 93 F
Wet Season: 61F
Deserts
A biome that is very dry and very hot. Plants and animals have special adaptations to live
in the dry, hot climate.
Climate
Animals that live in
Deserts are:
Snakes, spadefoot toad,
desert tortoises
Average Yearly Rainfall
LESS than 10 inches
Average Temperature:
Summer: 100 F
Winter: 45F
Tundra
Biome that is a treeless plain with very cold temperatures and little rainfall
Found in the Arctic, Antarctic, or on the tops of mountains
Two types: POLAR TUNDRA and ALPINE TUNDRA
Average Yearly Rainfall:
12 to 20 inches
Average Temperature:
Summer: 54 F
Winter -15 F
Animals that live in Tundra are: caribou,
insects, birds, musk, oxen, wolves
