* A biome is a large geographic area with similar climate and ecosystems

* Tundra

* Coniferous/Boreal Forest(Taiga)

* Deciduous Forest

* Tropical Rain Forest

* Grassland/Savannah

* Desert

• 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

In Canada, Alaska, northern Asia, and northern Europe

• 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.

Deciduous forests are between northeastern United States and Canada. Some are in the eastern United

States. Others grow in Europe and eastern Asia.

* Marine

* Freshwater

* 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
