Biomes

• Section 2
• World Plant Regions

Biomes

• What is a biome?
• A plant and animal community that covers a large
  area
• Plants are the most visible part
• Why?
• There are 5 basic biomes
• They can be broken down further
• Areas that share the same biome type also share
  climates and soil type

3
Forest Biome

• Forest biomes are covered with trees
• Forest biomes support
• A great variety of living things
• The Forest Biome can be broken down into 4 biomes
• Tropical Rain Forest
• Temperate Forest
• Boreal Forest
• Mediterranean Forest

4
Forest Biome

• Tropical Rain Forest
• Location Humid Tropical Regions

5
Forest Biome

• Tropical Rain Forest
• Description
• Warm Temps.
• Abundant water
• Year round plant growth
• Provides much humus to the soil
• Most complex ecosystem on the planet

6
Forest Biome

• Temperate Forest (Green)
• Location Mid-Latitude Climates

7
Forest Biome

• Temperate Forest
• Deciduous Forests
• Have 4 distinct seasons
• Trees lose their leaves during a certain season
• Ave. Temp. 50 Deg.
• Ave. Rainfall 30-60 in.

8
Forest Biome

• Temperate Forest
• Coniferous Forest
• Green year round
• Mainly in marine-west-
• coast climates

9
Forest Biome

• Temperate Forest
• Mixed Forest
• Where deciduous and coniferous trees blend
• Humid-Subtropical and Humid-Continental of the
  middle latitudes

10
Forest Biome

• Boreal Forest
• Location Subarctic Climate Regions (aqua)

11
Forest Biome

• Boreal Forest
• Description Mainly coniferous trees
• Can withstand extremely cold temperatures
• Decay is slow
• Boreal means northern
• Only found in N. Hemisphere

12
Forest Biome

• Mediterranean Forest
• Location Mid-Latitude Coasts
• Cover a very small portion of the earth

13
Forest Biome

• Mediterranean Forest
• Description Long, sunny, dry summers
• Chaparral-short trees and shrubs
• Drought resistant plants

14
Savanna Biome

• Location Between the Tropical Rain Forests and
  Deserts (Light green)

15
Savanna Biome

• Description
• Tropical Grassland with scattered trees and
  shrubs
• Supports herds of grazing animals and predators
• Savannas are spreading due to logging,
  farming,and over-grazing

16
Grassland Biome

• Location Yellow
• Mid Latitude
• Between temperate forests and deserts

17
Grassland Biome

• Description
• Semiarid climate
• Trees are found along rivers
• 2 Types
• Prairie Wetter, closer to forests
• Fertile soil
• Steppe Drier closer to deserts
• Low rainfall

18
Desert Biome

• Location Red
• Low and Mid Latitudes
• Desert climate regions

19
Desert Biome

• Description
• Plants survive using very little water
• Cacti
• Sage-brush

20
Desert Biome

• Some plants avoid dry weather
• Seeds survive underground
• When rain comes the seeds sprout

21
Tundra Biome

• Location dark blue
• Arctic regions of N. America, Europe and Asia
• Antarctic and high mountains

22
Tundra Biome

• Description
• Little plant growth and no trees
• Permafrost is present
• This area thrives during the short summer
• Lichens
• Moss
• Shrubs
• Birds
• Insects

23
Barren Regions

• Location (not on map)
• Far polar regions

24
Barren Regions

• Description
• Ice and snow all year
• No plant life or soil
• Animal life depends on the ocean for food
• Antarctica, Greenland, High mountain peaks
