* 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

* Tundra Tundra * Coniferous Forest Coniferous Forest * Deciduous Forest Deciduous Forest * Tropical Rain Forest Tropical Rain Forest * GrasslandGrassland * Desert Desert

Where is the tundra? Around the North Pole and near the Arctic Ocean Climate (weather) Very little precipitation Very cold all year Much ice / snow Plant Life No trees. Small ground plants & grasses. Soil type Permafrost: frozen most of the year (even in the spring and summer) Slushy when thawed.

Animals Life: Warm-blooded animals Insects in summer wolf ermine Reindeerducklemming marmot musk ox polar bear sandy hill crane snowy owl grass moss lichen grass lichen

Climate Medium rain/snow Long, cold winters Short summers Soil Type Poor soil. Smothered in needles Plant Life Heavy conifer forests (trees w/ needles & cones). Few small plants Animal Life Mostly warm-blooded. Many migrate or hibernate.

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

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

Climate Very warm all year round. Heavy rainfall. Rains almost everyday Gets almost 10 feet of rain every year.

Soil type Soil is ok—plants drain nutrients. Plant life Huge variety of trees  shaded ground. Big-leaf groundplants. Animal life Huge variety of warm and cold blooded animals

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.

Climate Hot summers, cool winters. Not enough rain for forests. Soil type Soil type Soil is ok for grasses, but often dry. Plant life Plant life Mostly small plants and grasses. Some scattered trees. Animal life Animal life Warm and cold blooded animals. Many are large or fast.

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 Land is usually flat Not a lot of trees The most important plant is __________. Examples: Wheat, rye and corn grass American Bison

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

* MarineMarine * FreshwaterFreshwater

* 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 barracuda star fishclown fishcrab flashlight fishgreen sea turtlekiller whaleshrimp

* 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
