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 worlds biomes. Each biome is discussed individually. The presentation shows each biomes location, climate, plant, and animal life.

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 biomes62

4 * Tundra Tundra * Coniferous Forest Coniferous Forest * Deciduous Forest Deciduous Forest * Tropical Rain Forest Tropical Rain Forest * Grassland Grassland * Desert Desert

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 caribouducklemming marmot musk ox polar bear sandy hill crane snowy owl

9 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

10 In Canada, Alaska, northern Asia, and northern Europe EuropeAsia Canada Alaska

11 Conifer trees (have cones) Have needles covered with wax Wax protects the needles from freezing cone needles Kinds of conifer trees pinefirspruce

15 Climate Summers are warm Winters are cold Gets 75 centimeters of rain every year (thats 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.

16 Deciduous forests are between northeastern United States and Canada. Some are in the eastern United States. Others grow in Europe and eastern Asia.

20 Climate Rains almost everyday Gets almost 10 feet of rain every year. Very hot all year long

21 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.

31 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

32 The largest grassland is in Africa. There are also grasslands in North America, South America, central Asia, and northern Australia.

33 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

34 Largest savannas are found in Africa There are only a few trees on the savanna Why dont 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

35 Grass Can live without a lot of rain Acacia tree Baobab tree

36 African elephant Black RhinocerosCheetah Giraffe HippopotamusHyena Lions Ostrich Warthog Wild Dog Zebra

37

38 There are __________ kinds of deserts. two Hot deserts and cold deserts Sahara DesertGobi Desert hot desert cold desert

39 In Africa, western North America, western Asia, central Australia, and western South America.

40 * 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

41 * can live there because the roots are close to the top of the ground and can get the water quickly. CactusAloe Barrel Cactus Prickly Pear Cactus

45 * MarineMarine * FreshwaterFreshwater

46 * 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

47 Many of the plants live near the top of the water they need the sunlight to help them grow and make food

48 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 fishclown fishcrab flashlight fishgreen sea turtlekiller whaleshrimp

49 * 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

50 * 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 cattailwater lily

51 bass carp mallards trout bull frog

52 * 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

53 * There are __________ land biomes: 6 ____________________ Tundra Coniferous Forest Deciduous Forest Tropical Rain Forest Grassland Desert * There are __________ water biomes: 2 ____________________ MarineFreshwater * The special kind of water is an ___________________. estuary
