Transcript Tropical Rain Forest

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 ____
6 land biomes and ___
2 water biomes
* Tundra
* Coniferous Forest
* Deciduous Forest
* Tropical Rain Forest
* Grassland
* Desert
• Climate
• Summers are warm 28 degrees Celsius
• Winters are cold 6 degrees Celsius
• Gets 75 centimeters of rain every year

• 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
• Cold and snowy
•30-85 cm of rain per year
• 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
•Evergreen trees do not lose their needles (leaves) every year.
Kinds of conifer trees
pine
spruce
fir
Moose
Hawk Owl
Beaver
Lynx
Wolf
Red Squirrel
Black bear
Wolverine
Snowshoe Rabbit
• Climate
• Rains almost everyday
• Gets almost 250 cm of rain every
year.
• Very hot all year long 34 °C to 20 °C
•Home to half of the Earth’s plant and
animal species.
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.
•
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
summer)
• Flat land with only a few small, thin trees
spring and
• Plants
• Fungi and algae
• They cover the rocks and ground
• Animals
wolf
ermine
caribou
marmot
duck
polar bear
lemming
sandy hill crane
musk ox
snowy owl
• 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.
•Winter: -40 degrees C
•Summer: 20 degrees C
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
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
Sahara Desert
Gobi 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: 40 degrees C
* and cool at night:10 degrees C
* 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
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
barracuda
flashlight fish
star fish
green sea turtle
clown fish
killer whale
crab

* 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
cattail
water lily
carp
bass
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
