4. Foldable
You will need 5 pieces of white paper. Stack them to make a foldable and staple the top.
Label the front “Biomes of the World”.

7. Ecosystems and Biomes 20. Biomes?
A group of land ecosystems with similar climates and organisms
Climate (temperature+precipitation)

8. Terrestrial Biomes vs. Aquatic Biomes
Terrestrial – 6 major land biomes
Aquatic- Freshwater and Marine
Ecosystems
Mountain Ranges- climate changes
as you increase in elevation

Tropical Rain Forest
Desert
Grassland
Deciduous Forest
Taiga
Tundra

10. Aquatic Biomes Freshwater- Streams, rivers, ponds and lakes
Estuary- where the freshwater of a river meets the salt water of the ocean (nursery)
Ocean- Intertidal zone, Neritic zone, and the Open ocean

11. Tundra

12. Did you know that the Arctic Tundra is the world's youngest biome?
*Found in the far north and on the tops of mountains.
*No trees are found in the tundra.
*It is the coldest biome average temp. -20 to -30 F
* Precipitation totals inches a year, which includes snow
*There are two types of tundra: arctic and alpine
Tundra

13. Artic Tundra *Has permafrost which stays frozen year round
Water is available and the surface is wet and soggy
Summer last for 6-10 weeks, temp high 45 F
Small shrubs, grasses, moss and lichens grow during the summer months.

14. Alpine Tundra Lots of sunshine and precipitation in the form of snow
Located above the tree line of tall mountains

15. The tundra is located above the taiga in the northern hemisphere
The tundra is located above the taiga in the northern hemisphere. It spans from most of Greenland, to parts of Alaska, northern Canada, and northern Russia.

17. Forests There are three types of forests…
1.) Temperate Deciduous Forests
2.) Tropical Rain Forests
3.) Taiga (Coniferous Forests/Boreal Forests)

18. Taiga

19. Taiga This biome has long cold winters
Has evergreen trees – trees that stay green all year long.
*Conifers are trees that produce seeds in cones and have needle-like leaves (pine trees)
*Animals in this biome often hibernate or migrate
*This is the largest biome
*AKA: coniferous forest and boreal forest

20. Taiga Rainfall – 35 - 75cm Temp.- Summer :70 F Winter : -65 to 30 F
The taiga is the largest of all land biomes and has long cold winters.
Animals of the taiga tend to be predators like the lynx and members of the weasel family like wolverines, bobcat, minks and ermine. They hunt herbivores like snowshoe rabbits, red squirrels and voles. Red deer, elk, and moose can be found in regions of the taiga where more deciduous trees grow.

21. The taiga is only found in the northern hemisphere and it’s the largest biome

23. POD # 25 Tundra What is the average temp in the tundra?
What is the average rainfall in the tundra?
What is the Permafrost?
What are the two types of tundra?
Name three animals that live in the tundra?

24. Tropical Rain Forest

25. Tropical Rain Forest More species live here than any other biome
Canopy – treetops in the rainforest. Most animals live there
Very little light reaches the ground b/c of the canopy
This is the wettest and warmest biome
Rainfall – up to 400cm
Temp.- Daytime– 34C, 93F
Nighttime– 20C, 68F

26. The world’s rainforest’s are found in tropical locations near the equator.

28. Temperate Deciduous Forest

29. Temperate Deciduous Forest
Deciduous means “to fall off” – the trees in this region have leaves that fall off.
We live in a temperate forest!
Rainfall – 75 – 125cm
Temp.- Summer – 28C, 82F
Winter– 6C, 43F

30. Temperate Deciduous Forest’s are typically found in the northern hemisphere.
Click to the next slide to see plants and animals commonly found in this biome

32. POD # 26 Tropical Rain Forest
Where is this biome located?
Where do all of the animals live?
Name three animals that are from this biome?
What are two resources that we get from the Tropical Rain Forest?
How much rain does it get per year?

33. Grasslands -Grasses are the main vegetation.
-There biomes are typically found between forests and deserts.
-These biomes exist on every continent except Antarctica.
-They are also known as plains, prairies, savannas, and steppes.

34. Temperate Grassland

35. Temperate Grasslands
This biome has mixed grasses with various plants and a few trees
Rainfall – 25-75cm
Temp.- Summer – 30C, 86F
Winter – 0C, 32F

36. Savanna

37. Savanna Tropical grassland with scattered clumps of trees.
It has a rainy season and a dry season.
The majority of the world’s savannas are in Africa.
Rainfall – 150cm
Temp.- Rainy Season : 16C, 61F
Dry Season : 34C, 93F

40. Desert

41. Desert Hot and dry with a variety of plants and animals.
Animals are most active at night (nocturnal)
This is the biome with the least rainfall
Rainfall – less than 25cm
Temp.- Summer: 49C, 100F
Winter : 7C, 45F

42. The Earth’s Deserts

How is it different from the Taiga biome?
What is the average rainfall for the Taiga?

46. Aquatic Ecosystems

47. Aquatic Ecosystems 70-75% of Earth is made up of water.
*3% of water is fresh water, 97% is salt water.
*Less than 1% of fresh water is available for drinking.
*The main producers in aquatic biomes are algae.

48. Freshwater Ecosystems
The water is drinkable and has no salt
Examples: streams, rivers, lakes, ponds, swamps, marshes
A small stream that leads into a big stream is called a tributary
A place where the water is above ground for the majority of the year is called a wetland
A swamp has many trees, but a marsh has few trees
5 great lakes – Huron, Ontario, Michigan, Erie, Superior
Longest river in the world – Nile River

50. Marine Ecosystems The water is undrinkable and has lots of salt
Salt is the main abiotic factor in a marine ecosystem
Examples: oceans, seas, gulfs, bays
The place where freshwater from a river and saltwater from the ocean mix is called an estuary.
Most organisms in a marine ecosystem live near the shore
