1. SWBAT define biome and give examples of what makes them unique.

Based on this map, what biomes are common in the United States?

2. Biomes

3. What is a biome?
A biome is a large area of similar climate (temperature and rainfall) and vegetation

4. Examples of biomes Land: Water: Tundra Ocean Taiga Fresh water
Deciduous forest Estuaries
Tropical rainforest
Grasslands
Desert

5. Tundra

6. Tundra Climate Average temperature -18˚F
Average precipitation inches
Ground is permanently frozen below 10 inches
Short summer growing season with temperatures to 54˚F

7. Tundra vegetation
No trees: most common vegetation is moss and lichen

8. Tundra animals

9. Taiga (coniferous forest)

10. Taiga climate Long severe winter and short summer
Winter temp: -65˚F to 30˚F
Summer temp: 20˚F to 70˚F
Average precipitation 15-20”

11. Taiga vegetation
Coniferous (evergreen) forest

12. Taiga animals

13. Temperate deciduous forest

14. Deciduous forest climate
Average annual temperature 50˚F
Four distinct seasons
Average rainfall 30-60”

15. Deciduous forest vegetation
Deciduous trees—trees that lose their leaves in the winter
Shrubs and flowering plants

16. Decidous forest animals

17. Tropical rainforest

18. Tropical rainforest climate
Temperature range 68˚F to 86˚F
Annual rainfall over 80”
Very humid

19. Rainforest vegetation
More than half the world’s plants
Layers: canopy, understory, forest floor

20. Rainforest animals
More than half the species in the world live in the rainforest

21. Grasslands

22. Grasslands climate Temperature has large range: -40˚F to 90˚F
Rainy season and dry season
10-30” rain in temperate grasslands; 25-60” in tropical grasslands

23. Grasslands vegetation
Not enough moisture for more than a handful of trees

24. Grasslands Animals

25. Desert

26. Desert climate Day-night temperature extremes
Ave. daytime temp 100˚F, ave. nighttime temp below 50˚F
Less than 10” rainfall a year

27. Desert vegetation
Sparse, specially adapted plants

28. Adaptation
An adaptation is an inherited characteristic that helps an organism survive and reproduce in its environment.
