1. All About Land Biomes
Biome: A geographic area on Earth that contains ecosystems with similar biotic and abiotic features.

2. a biome that receive very little rain.
Desert Biome:
a biome that receive very little rain.

3. Desert Biome Earths driest ecosystem.
Most deserts are hot during the day and cold during the night. (Others like Antarctica remains cold all of the time)
Rainwater drains away quickly because of thin, porous soil.

4. Desert Biome Animals and Plants (Biotic Factors)
Lizards
Bats
Woodpeckers
Snakes
Spiny cactus
Thorny shrubs

5. Desert Abiotic Factors
Receives less than 10 inches (25 cm) of rain per year.
The average daytime temperature is 100°F (38°C) while at night the average temperature is 25°F (-4°C). This large temperature difference is due to low amount of moisture in the desert air.

7. Grassland Biome: Areas where grasses are the dominate plants.

8. Grassland Biome Also called “prairies”, “savannas” and “meadows”
Have wet and dry seasons
Trees grow along moist banks of streams and rivers.
Wildflowers bloom during wet seasons

9. Grassland Biome Animals and Plants (Biotic Factors)
Elk
Rabbits
Prairie dogs
Hawks
Coyotes
African savannas contain – giraffes, zebras and lions.
Wildflowers
Worlds “Breadbasket” (wheat, corn, oats, rye, barley)
Wild oats
foxtail
buffalo grass

10. Grassland Abiotic Factors
There is an average of 19 – 36 inches (50-90 cm) of rainfall a year.
The average temperature ranges from -4°F to 86°F
(-20°C to 30°C) per year.
Grasslands are generally open and continuous, fairly flat areas of grass.
The soil is porous, with rapid drainage of water.

12. Tropical Rainforest Biome: The forest that grows near the equator.

13. Tropical Rainforest Biome
Forests that receive large amount of rain
Has dense growth of tall, leafy trees.
Weather is warm and wet year-round.
Half of Earths species live in tropical rainforest.

14. Tropical Rainforest Animals and Plants (Biotic Factors)
Mosses
Ferns
Orchids
Insects- beetles, termites, ants, bees and butterflies
Parrots
Snakes
Frogs
Flying squirrels
Monkeys

15. Tropical Rainforest: Abiotic Factors
Soil is shallow and easily washed away by rain
Less than 1% of sunlight that reach the top of the forest trees also reach the forest floor.
Yearly temperature is between 68 °F (20 °C) and 93 °F (34 °C)
Rainfall is often more than 100 inches (254 cm) a year.

16. Tropical Rainforest Yearly Temperature

17. Temperate Rainforest Biome: Regions of Earth between the tropics and the polar circles.

18. Temperate Rainforest Biome
Temperate means “not too extreme”
Moist ecosystems mostly in coastal areas.
Not as warm as tropical rainforests.
Winters are mild and rainy.
Summers are cool and foggy.

19. Temperate Rainforest Animals and Plants (Biotic Factors)
Spruce
Fungi
Redwood Tree
Fir
Vines
Mosquitos
Butterflies
Salamanders
Deer
Raccoons

20. Temperate Rainforest: Abiotic Factors
Soil is rich and moist.
The temperature is generally between -20°F and 90°F (-29°C and 30°C)
There is lots of rain throughout the year, usually between 30 and 60 inches ( cm) of rain.

21. Temperate Rainforest Yearly Temperature

22. Temperate Deciduous Forest Biome: Dominated by trees that lose their leaves each year.

23. Temperate Deciduous Forest Biome
These forests are the most common forest ecosystems in the United States.
Winter temperatures are often below freezing.
Snow is common.
Summers are hot and humid.

24. Temperate Deciduous Forest Animals and Plants (Biotic Factors)
Maple
Oaks
Birches
Foxes
Opossums
Chipmunks
Monarch

25. Temperate Deciduous Forest: Abiotic Factors
Soil is rich in nutrients and supports a large amount of diverse plant growth.
The average temperature of the forest is about 50°F (10° C).
The average amount of rainfall in the forest is 30 to 60 (76 – 152 cm) inches a year.
As the seasons change, so do the colors of the leaves of the deciduous.

26. Temperate Deciduous Forest Yearly Temperature

27. Taiga Biome: A forest biome consisting mostly of conebearing evergreen tree.

28. Taiga Biome Exist only in the northern hemisphere.
Winters are long, cold and snowy.
Summers are short, warm and moist.

29. Taiga Biome Animals and Plants (Biotic Factors)
Evergreen Trees
Pine
Fir
Owls
Mice
Moose
Bears

30. Tiaga Biome: Abiotic Factors
Soil is thin and acidic.
The average temperature per year is between 26°F-50 (-3°C- 10°C).
The totally yearly precipitation is between inches ( cm).

31. Tiaga Biome Yearly Temperature

32. Tundra Biome: Cold, dry and treeless.

33. Tundra Biome
Most tundra's are south of the north pole, but also exist in mountainous areas at high altitudes.
Winters are long, dark and freezing
Summers are short and cool

34. Tundra Biome Animals and Plants (Biotic Factors)
Shallow-rooted mosses and grasses
Lichens
Lemmings
Water birds
Polar bears
Arctic fox
White wolves

35. Tundra Biome: Abiotic Factors
Permafrost- a layer of permanently frozen soil which prevents deep root growth.
The average winter temperature is -30° F (-34° C), but the average summer temperature is 37-54° F (3-12° C ).
Yearly precipitation, including melting snow, is 6 to 10 inches (15 to 25 cm).
