Biomes of the World 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.
Biomes of the World
What are biomes? * 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
Land Biomes *Tundra *Coniferous (Boreal) Forest *Deciduous Forest *Tropical Rain Forest *Grassland *Desert
Tundra • 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 and Animals of the Tundra • Plants • Fungi and algae • They cover the rocks and ground • Animals caribou duck lemming musk ox wolf sandy hill crane polar bear marmot snowy owl ermine
Invasive Species of the Tundra • Plants Japanese Knotweed Austrian Pine • Animals Canada Goose Red Deer Arctic Tern European Crab
Coniferous (Boreal) Forest • 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
Where are coniferous forests? Alaska Canada Europe Asia In Canada, Alaska, northern Asia, and northern Europe
Plants of the Coniferous Forest • Conifer trees (have cones) • Have needles covered with wax • Wax protects the needles from freezing cone needles Kinds of conifer trees pine spruce fir
Moose Beaver Wolf Black bear Wolverine Red Squirrel Hawk Owl Lynx Animals of the Coniferous Forest Snowshoe Rabbit
English Holly Grey Squirrel European Starling Asian Gypsy Moth English Ivy Invasive Species of the Coniferous Forest
Deciduous Forest • 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.
Where Are Deciduous Forests? Deciduous forests are between northeastern United States and Canada. Some are in the eastern United States. Others grow in Europe and eastern Asia.
Plants of the Deciduous Forest * Trees * Flowers * Oak * Hickory * Lily of the valley * Maple * Beech * Star Flower
Animals of the Deciduous Forest Eagle Brown Bear Black Bear Chipmunk Raccoon Porcupine Red Fox White-tailed Deer Mouse Coyote
Invasive Species of the Deciduous Forest Asian Gypsy Moth Screwworm Nun Moth Wineberry English Ivy Lady Bug Purple Loosestrife
Tropical Rain Forest How much rain is that? • Climate • Rains almost everyday • Gets almost 10 feet of rain every year. • Very hot all year long Rainforest Illinois
Where are Tropical Rain Forests? 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.

Wow! What a sight!
Grasslands • 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
Where are grasslands? Savannas Temperate Grasslands The largest grassland is in Africa. There are also grasslands in North America, South America, central Asia, and northern Australia.
Temperate Grasslands (Prairie) • 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 __________.
Tropical Grasslands (Savanna) • 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
Plants of the Savanna • Grass • Can live without a lot of rain • Acacia tree • Baobab tree
Black Rhinoceros Cheetah Wild Dog African elephant Giraffe Animals of the Savanna Zebra Ostrich Hippopotamus Hyena Warthog Lions
Fire Ant Wild Goat Invasive Species of the Savanna Gum Arabic Tree Grey Fox
Desert two There are __________ kinds of deserts. • Hot deserts and cold deserts cold desert hot desert Sahara Desert Gobi Desert
Where are deserts? In Africa, western North America, western Asia, central Australia, and western South America.
Hot Deserts * Climate * gets less than 25 centimeters of rain every year * hot during the day and cool at night Cold Deserts * Climate * gets less than 25 centimeters of rain every year * cold all of the time
Plants of the Deserts * 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
