1. Unit 2 – Biomes

2. Ecology  Interactions + Interdependence of Life

3. Levels of Organization in the Biosphere

4. Biome Most inclusive (broadest) Group of ecosystems with similar climate and communities At least 10 different biomes across the globe... What might these be?

5. The Major Biomes Tropical Rainforest Tropical Dry Forest Tropical Savanna Temperate Grassland Temperate Forest Desert Tundra Temperate Woodland Northwestern Coniferous Forest Boreal Forest (Taiga)

6. The Major Biomes Tropical Rainforest Tropical Dry Forest Tropical Savanna Temperate Grassland Temperate Forest Desert Tundra Temperate Woodland Northwestern Coniferous Forest Boreal Forest (Taiga)

7. Tropical Rainforest Major FeaturesAbiotic FactorsDominant Plants More species than any other biome Diverse canopy and understory Hot and wet year round Lack of nutrients in soil Broad-leaved evergreens Ferns Woody vines

8. Tropical Rainforest

9. Desert Major FeaturesAbiotic FactorsDominant Plants Less than 25 cm of rain per year Extreme daily temp changes Organisms tolerate extreme conditions Low precipitation Variable temps Soil = lots of minerals, little organic matter Cacti, succulents Low shrubs/bushes

10. Desert

11. Temperate Grassland Major FeaturesAbiotic FactorsDominant Plants Plains and prairies Maintained by fires and grazing Fire-resistant plants Warm to hot summers; cold winter Moderate precip Fertile soil Grasses and herbs/wildflowers

12. Temperate Grassland

13. Temperate Forest Major FeaturesAbiotic FactorsDominant Plants Mixed tree types Our main biome in Michigan Cold winters, warm summers Year round precip Fertile soils Deciduous and coniferous trees Shrubs, herbs, mosses, ferns

14. Temperate Forest

15. Boreal Forest (Taiga) Major FeaturesAbiotic FactorsDominant Plants Northern edge of temperate forests Long cold winters, short mild summers Moderate precip Lack of nutrients in soil Coniferous trees Small berry shrubs

16. Boreal Forest (Taiga)

17. Tundra Major FeaturesAbiotic FactorsDominant Plants Permafrost layer Only topsoil defrosts in summer Arctic region Windy, low precip Short summers Long, cold, dark winters Little soil Mosses Lichens Short grasses

18. Tundra
