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.

* 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 biomes6 2

* Tundra

* Coniferous Forest

* Deciduous Forest

* Tropical Rain Forest

* Grassland

* 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)

• Flat land with only a few small, thin trees

• 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

• 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

In Canada, Alaska, northern Asia, and northern Europe

• Conifer trees (have cones)

• Have needles covered with wax

• Wax protects the needles from freezing

Snowshoe Rabbit

• 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.

Deciduous forests are between northeastern United States and Canada. Some are in the eastern United

States. Others grow in Europe and eastern Asia.

* Trees

* Oak * Hickory

* Maple * Beech

* Flowers

* Lily of the valley

* Star Flower

Eagle Brown Bear Black Bear Chipmunk

Raccoon Porcupine Red Fox White-tailed Deer

Mouse Coyote

• Climate

• Rains almost everyday

• Gets almost 10 feet of rain every year.

• Very hot all year long

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 _____ 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

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

• 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

• 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

African elephant

Black Rhinoceros

Cheetah Giraffe

Hippopotamus Hyena Lions

Ostrich

Warthog

Wild Dog

Zebra

There are __________ kinds of deserts.two

• Hot deserts and cold deserts

Sahara Desert Gobi Desert

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

* can live there because the roots are close to the top of the ground and can get the water quickly.

* Marine

* Freshwater

* 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

• 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

flashlight fish green sea turtle

killer whale shrimp

* 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 itsalt

* 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

bass carp

mallards

trout

bull frog

* 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

* There are __________ land biomes: 6
