1Biomes of the WorldThis 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.
3What 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 biomes62
5Tundra Climate (weather) Where is the tundra? Around the North Pole and near the Arctic OceanClimate (weather)Very cold and dryTemperature: less than -5°COnly has 25 centimeters or less of rain every yearWhat the land looks likePermafrost: the dirt that is always frozen (even in the spring and summer)Flat land with only a few small, thin trees
6Plants and Animals of the Tundra Fungi and algaeThey cover the rocks and groundAnimalscaribouducklemmingmusk oxwolfsandy hill cranepolar bearmarmotsnowy owlermine
9Coniferous Forest Climate Cold and snowy What the land looks like In the winter:Ground is frozenIn the spring:Taiga: swampy forestSnow melts and the ground becomes wet and swampy because the deeper ground is frozen
10Where are coniferous forests? AlaskaCanadaEuropeAsiaIn Canada, Alaska, northern Asia, and northern Europe
11Kinds of conifer trees pine spruce fir Conifer trees (have cones) Have needles covered with waxWax protects the needles from freezingconeneedlesKinds of conifer treespinesprucefir

15Deciduous Forest Climate What is special about deciduous trees? Summers are warmWinters are coldGets 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 springThe leaves on the ground make the dirt better and help plants grow.
16Where 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.

20Tropical Rain Forest How much rain is that? Rainforest Illinois ClimateRains almost everydayGets almost 10 feet of rain every year.Very hot all year longRainforestIllinois
21Where 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.

31Grasslands There are _____ kinds of grasslands. two Temperate grasslands: called prairiesTropical grasslands: called savannasClimateAll grasslands get between 25 and 75 centimeters of rain every year.Coniferous forest
32Where 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.
33Temperate Grasslands (Prairie) Some are found in the United StatesIllinois is on the prairie, so we live in the temperate grasslands.Land is usually flatNot a lot of treesgrassThe most important plant is __________.
34Tropical Grasslands (Savanna) Largest savannas are found in AfricaThere are only a few trees on the savannaWhy don’t a lot of trees grow?Savanna does not get a lot of rainPeople set the grass on fire to stop trees from growingAnimals eat the trees before they can start growing tall
35Plants of the Savanna Grass Can live without a lot of rain Acacia tree Baobab tree

38Desert two There are __________ kinds of deserts. Hot deserts and cold desertscold deserthot desertSahara DesertGobi Desert
39Where are deserts?In Africa, western North America, western Asia, central Australia, and western South America.
40Hot Deserts Cold Deserts * Climate * gets less than 25 centimeters of rain every year* hot during the day and cool at nightCold Deserts* Climate* gets less than 25 centimeters of rain every year* cold all of the time
41Plants of the Deserts* can live there because the roots are close to the top of the ground and can get the water quickly.CactusAloeBarrel CactusPrickly Pear Cactus

46The Marine Biome ocean different organisms live in each area * 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 toobecause of these things, the ocean is divided into different areasdifferent organisms live in each area* The water that is very deep has cold temperatures, high pressures, and is very dark
47Marine Plant Life barnacles coral Many of the plants live near the top of the waterthey need the sunlight to help them grow and make foodbarnaclescoral
48Marine Animal LifeMost marine organisms live near the top of the water or close to landMany animals dig down into the sand or hang on to rocks, so they do not get lost in the seaOther larger animals live where the water is deepbarracudastar fishclown fishcrabflashlight fishgreen sea turtlekiller whaleshrimp
49The Freshwater Biome salt * Freshwater means it does not have _______________ in it* Includes still water and moving water* Examples of still water * Examples of moving water* lakes and ponds * rivers and streams
50Freshwater Plant Life* 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 watercattailwater lily

52A Special Kind of Water * 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
