1. Biomes Main Points

2. Terrestrial Biomes Tropical Rainforest Tropical Grasslands
Temperate Grasslands
Temperate Deciduous Forest
Desert
Tundra
Taiga

3. Tropical Rainforest Characterized by 100 inches of rain a year
Continuous canopy of trees
Very humid
Dry & wet seasons

4. Tropical Grasslands (Savanna)
Characterized by grasses, scattered trees (ex- acacia)
Dry and wet seasons
Warm to hot biome

5. Temperate Grasslands (Prairies)
Also characterized by grasses and low growing plants
Hot summers & cold winters
Depend on wildfires

6. Temperate Deciduous Forest
Characterized by deciduous trees (lose their leaves) and moderate temperatures
4 distinct seasons
Plenty of rain

7. Desert Characterized by lack of rain (less than 10 inches a year)
Most are hot, but some are cold
Very dry, sandy soil

8. Tundra Characterized by extremely cold temperatures and dry weather
Has permafrost  frozen soil
Mostly barren, treeless land
Long winters, short summers

9. Taiga
Characterized by coniferous trees (do not lose leaves), also called evergreens
Cold temperatures

10. Aquatic Biomes Freshwater Marine Rivers/streams Lakes/ponds
Wetlands marsh, swamp, bogs, prairie pothole
Marine
Ocean
Coral Reefs
Estuaries

11. Rivers/Streams Rivers are large bodies of moving water
Streams are smaller bodies of moving water

12. Lakes/Ponds Lakes are large bodies of water surrounded by land
Ponds are smaller bodies of water surrounded by land

13. Lake/Pond zones

14. Wetlands
Marsh has non-woody plants
Swamps have wood plants

15. Oceans
Large, open salt water
Largest marine body

16. Marine Zones

17. Coral Reefs
Long range of “polyps” built up into rocky structures in a marine ecosystem

18. Estuaries Areas where freshwater rivers flow into the ocean
Where fresh and salt water meet & mix
Important for ecosystem health
