3. Background
Biome: A large geographical area of distinctive plant and animal groups, which are adapted to that particular environment
Biomes are largely determined by…
Climate
Rainfall
Temperature
Geography
Landforms
Altitude

4. Biomes of the world
There are 3 broad biome classifications of the world, which can each be further subdivided:
Marine biomes
Freshwater biomes
Land biomes
Taiga
Rainforest
Tundra
Desert
Temperate
Grasslands
Savannah

5. How are Biomes Named? According to their plant life
Plant life determine which organisms live there

6. Organisms in Biomes
Plants & animals have adapted to specific environments
Threatened by human activities

7. Biomes and Soil Deciduous Forest- good soil, lush plant life
Deciduous = trees that drop their leaves
Grasslands-good soil, lush plant life
Desert-sandy soil, NOT much plant life
Taiga-good soil, lush plant life (conifer trees)
Tundra- permafrost of soil

8. Water Ecosystems Either Freshwater or Marine Freshwater = no salt
Marine = salt water

9. Freshwater Ecosystems
Includes lakes, ponds, rivers, streams and wetlands
Distinguished by:
Depth of the water
How fast the water moves
Availability of mineral nutrients, sunlight, and oxygen

10. Marine Ecosystem Identified by the presence of salt water
Includes estuaries, coral reefs, oceans and ice caps

11. Tropical Rainforest Typically found near the equator
Receives more than 200 cm of rain annually
Temperatures typically fall between 20oC and 25oC for the entire year
As many as 50% of all the world’s animal species may be found here

12. Tropical Savanna Grasslands with a few scattered trees
Experience a wet and dry season
Hot temperatures
Annual rainfall is between 50 and 127 cm
More species of grazing mammals than any other biome

13. Desert Typically found between 25o and 40o latitude
Receives less than 25 cm of rain each year
Temperatures typically range between 20oC and 25oC but some extreme deserts can reach temperatures higher than 38oC and lower than –15oC

14. Chaparral
Found between 32o and 40o latitude on the west coast of continents
Receives between 35 and 70 cm of rain, usually in the winter
Extremely resistant to drought and weather events

15. Grassland
Because of the dry climate, trees are found only near water sources such as streams
Usually receives between 50 and 90 cm of rainfall each year
Summer temperatures can reach up to 38oC, and winter temperatures can fall to –40oC

16. Temperate Deciduous Forest
Moderate climate
Most trees will lose their leaves in the winter
Temperatures range between –30oC and 30oC
Averages from 75 to 150 cm of precipitation
Well developed understory

17. Temperate Boreal Forest
Also known as Taiga
Typically found between 45o and 60o North latitude
Cold climate with summer rains
Very few reptiles
Limited understory
Snow is primary form of precipitation (40 – 100 cm annually)

18. Tundra Means treeless or marshy plain
Characterized by permafrost – permanently frozen soil starting as high as a few centimeters below the surface – which severely limits plant growth
Winter temperatures average –34oC while summer temperatures usually average below 10oC
Low precipitation (15–25 cm per year) but ground is usually wet because of low evaporation

19. Koppen classification
The modified Koppen classification uses six letters to divide the world into six major climate regions, based on average annual precipitation, average monthly precipitation, and average monthly temperature. . . (click the links for a map of each classification)

A for Tropical Humid
B for Dry
C for Mild Mid-Latitude
D for Severe Mid-Latitude
E for Polar
H for Highland (this classification was added after Köppen created his system)

20. Koppen Classification
Each category is further divided into sub-categories based on temperature and precipitation. For instance, the U.S. states located along the Gulf of Mexico are designated as "Cfa." The "C" represents the "mild mid-latitude" category, the second letter "f" stands for the German word feucht or "moist," and the third letter "a" indicates that the average temperature of the warmest month is above 72°F (22°C). Thus, "Cfa" gives us a good indication of the climate of this region, a mild mid-latitude climate with no dry season and a hot summer.

22. North Carolina North Carolina is in the temperate deciduous biome
4 seasons every year
Relatively large amounts of rain
Animals and plants with special adaptations for changing seasons
