Chapter 6 Goals

• Explain what biomes are
• Explain how biomes are characterized
• Explain how latitude and altitude affect
  vegetation

3
What are the differences?Climate, Biology,
Limiting Factors, Adaptations?
4
Things Change?

• Fossil evidence suggests that the frozen
  continent of Antarctica was once covered in
  temperate forest.

5
Earths Biomes

• Groups of terrestrial ecosystems that share
  biotic and abiotic conditions
• 8 primary biomes
• Tropical Rain Forest
• Tropical Savanna
• Desert
• Temperate Forest
• Temperate Grassland
• Chaparral
• Taiga or Boreal Forest
• Tundra
• 1 secondary biome
• Polar Ice

• Climate Average conditions, including
  temperature and precipitation, over long periods
  of time in a given area
• Weather Day-to-day conditions in Earths
  atmosphere
• Climatographs Diagrams that summarize an areas
  average monthly temperature and precipitation
• Each biome has a set of characteristic organisms
  adapted to its particular climate conditions.

Latitude and Altitude

• Latitude is the distance north or south from the
  equator
• expressed in degrees
• Altitude is the height of an object above a
  reference point, such as sea level or the Earths
  surface
• expressed in meters or feet

17
Latitude and Altitude

• Climate varies with latitude and altitude
• For example, climate gets colder as latitude and
  altitude increase. This is why it gets colder as
  you move further up a mountain.

18
Latitude and Altitude

• As latitude and altitude increase, biomes and
  vegetation change
• Trees of tropical rainforests usually grow closer
  to the equator
• Mosses and lichen of the tundra grow closer to
  the poles
• The temperate region includes biomes such as
  temperate forests and grasslands
• usually have moderate temperatures and fertile
  soil ideal for agriculture

Chapter 6 Summary

• A biome is a group of terrestrial ecosystems that
  share biotic and abiotic conditions.
• Biomes are characterized by temperature,
  precipitation and type of plants animals.
• As latitude and altitude increase, biomes and
  vegetation change.
