1. This presentation was developed for a middle school/junior
high science class. Through use of this presentation and
their science book, students will be able to identify and
name important characteristics of the world’s biomes. Each
biome is discussed individually. The presentation shows
each biome’s location, climate, plant, and animal life.
2.
3. * A biome is an area that has the same climate (weather)
and the same organisms that live there.
* Biomes help scientists describe the world.
* There are ____ land biomes and ___ water biomes
6 2
5. • 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)
• Flat land with only a few small, thin trees
6. • Plants
• Fungi and algae
• They cover the rocks and ground
• Animals
wolf
ermine
caribou duck lemming
marmot
musk ox
polar bear sandy hill
crane
snowy owl
10. • 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
11. In Canada, Alaska, northern Asia, and northern Europe
Europe Asia
Canada
Alaska
12. • Conifer trees (have cones)
• Have needles covered with wax
• Wax protects the needles from freezing
cone
needles
Kinds of conifer trees
pine fir
spruce
13. Moose Beaver Wolf Black bear
Hawk Owl Lynx
Wolverine
Red Squirrel
Snowshoe Rabbit
17. • Climate
• Summers are warm
• Winters are cold
• Gets 75 centimeters of rain every year
(that’s over 2 feet of rain!)
• 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.
18. Deciduous forests are between northeastern United States and
Canada. Some are in the eastern United States. Others grow in
Europe and eastern Asia.
19. * Trees
* Oak * Hickory
* Maple * Beech
* Flowers
* Lily of the valley
* Star Flower
20. Eagle Brown Bear Black Bear Chipmunk
Raccoon Porcupine Red Fox White-tailed Deer
Mouse Coyote
23. • Climate
• Rains almost everyday
• Gets almost 10 feet of
rain every year.
• Very hot all year long
24. 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.
35. • There are _____ kinds of grasslands.
two
• Temperate grasslands: called prairies
• Tropical grasslands: called savannas
• Climate
• All grasslands get between 25 and 75 centimeters of rain
every year.
Coniferous forest
36. The largest grassland is in Africa. There are also grasslands
in North America, South America, central Asia, and northern
Australia.
37. • Some are found in the United States
• Illinois is on the prairie, so we live in the temperate
grasslands.
• Land is usually flat
• Not a lot of trees
• The most important plant is __________.
grass
38. • 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
39. • Grass
• Can live without a lot of rain
• Acacia tree • Baobab tree
40. African elephant Black Rhinoceros Cheetah Giraffe
Hippopotamus Hyena Lions
Ostrich
Warthog
Wild Dog
Zebra
43. There are __________ kinds of deserts.
two
• Hot deserts and cold deserts
Sahara Desert Gobi Desert
hot desert cold desert
44. In Africa, western North America, western Asia, central Australia,
and western South America.
45. * 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
46. * can live there because the roots are close to the top of the
ground and can get the water quickly.
Cactus Aloe
Barrel
Cactus
Prickly Pear
Cactus
52. * The marine biome is the _________________ biome.
ocean
* 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
53. • Many of the plants live near the top of the water
• they need the sunlight to help them grow and make food
54. • 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
barracuda star fish clown fish crab
flashlight fish green sea turtle killer whale shrimp
56. * Includes still water and moving water
* Examples of still water * Examples of moving water
* lakes and ponds * rivers and streams
* Freshwater means it does not have _______________ in it
salt
57. * 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
cattail water lily
60. * Estuary
* border between a freshwater biome and a marine biome
* are salt marshes, lagoons, swamps, and mouths of rivers that go
into the ocean
* are a mixture of freshwater and salt water
* some scientists believe estuaries are another biome, other
scientists believe estuaries are an ecosystem
* not very deep, so sunlight gets to all the water
* have many fish and plants
61. * There are __________ land biomes:
6
