What is a Biome?
  • Biome A group of land ecosystems with similar
    climates and organisms.
  • Ecosystem The community of organisms that live
    in a particular area, along with their nonliving
    surroundings.
  • Biotic All living things in an ecosystem
    (plants, animals, bacteria, etc.)
  • Abiotic Non-living things in an ecosystem
    (water, rocks, soil, light, rainfall, etc.)

3
How many biomes are there and what are they?
  • There are 6 major biomes
  • Rain Forests
  • Desert
  • Grassland
  • Deciduous forest
  • Boreal forest
  • Tundra

4
Rain Forest Biome
  • Two types
  • Temperate Rain Forests found in the NW US.
  • Tropical Rain Forests found along the equator.
    Sometimes called Jungles.

5
Temperate Rain Forest
  • gt 300cm of rain/yr.
  • Huge hardwood trees
  • Moderate temperatures

6
Temperate Rain Forest
7
Tropical Rain Forest
  • Close to equator.
  • Warm and humid year round
  • Distinct tree layers (strata)
  • More biodiversity than any other biome!

8
Tropical Rain Forest Biome
9
Desert Biome
  • lt 25cm of rain per year.
  • Evaporation gt precipitation
  • Big temperature shifts daily
  • Found outside of the equator
  • Organisms need special adaptations to survive.

Desert Biomes
11
Grassland Biome
  • Middle Latitudes
  • Prairie mostly grasses and other non-woody
    plants
  • 25-75cm of rain/yr.
  • Savanna Grasses, small shrubs, and small trees.
  • up to 120cm of rain/yr.

12
Grassland Biomes
13
Temperate Deciduous Forest Biome
  • Deciduous trees loose their leaves annually.
  • Rain 50cm/yr.
  • Large variation in temp. over the yr.

14
Temperate Deciduous Forest
15
Boreal Forest Biomes
  • AKA Taiga
  • Located in colder regions in the upper middle
    latitudes
  • Trees are coniferous.
  • Seeds are in cones and leaves are needle shaped.

16
Boreal Forest Biomes
17
Tundra Biome
  • Extremely dry and cold
  • Most soil is frozen yr. round, upper area that
    defrosts permafrost
  • Plants mosses, grasses, shrubs and dwarf trees.
  • Shallow ponds/marshy areas in the summer.
  • Located in the Northern Hemisphere and north of
    the Arctic Circle.
