Biotic and Abiotic Factors

• Abiotic factors are essentially non-living
  components that effect the living organisms (ie
  cloud cover, seasons, location, altitude)
• Biotic factors are all the living things or their
  materials that directly or indirectly affect an
  organism in its environment.   This would include
  organisms, their presence, parts, interaction,
  and wastes

Tropical Rainforest

Tropical Rainforest

• A hot, humid biome near the equator, with much
  rainfall and a wide variety of life
• Vegetation trees, vines, fungi, broadleaf woody
  species-thin bark, shallow roots, buttresses,
  vines
• Animals More species of insects, reptiles, and
  amphibians than any place else, small mammals,
  birds
• Wet season, short dry season, hot temperature

Temperate Deciduous Forest
A forest biome with many kinds of trees that lose
their leaves each autumn
12
Temperate Deciduous Forest

• Moisture low, distributed throughout year
• Temperature warm summers, cold winters
• Vegetation deciduous broadleaf-trees, shrubs,
  herbs, mosses
• Animals mammals, birds, insects, reptiles

Taiga (Boreal Forest)

• A cool forest biome of conifers in the upper
  Northern Hemisph-ere

15
Taiga

• Moisture moderate, varies throughout the year
• Temperature cold winters, cool summers
• Vegetation evergreens, shrubby ground cover
• Animals birds, mammals

16

17
Temperate Rainforest
Temperate rainforests are coniferous or broadleaf
forests that occur in the temperate zone and
receive high rainfall.
18
Temperate Rainforest

• Moisture Abundant precipitation 200400 cm, rain
  and snow.
• Temperature Cool temperatures, rarely below 5F
  or above 100F
• VegetationDiversity of conifers and hardwoods,
  many tall and old.
• Animals mammals(deer, bears), slugs, birds

Desert
A sandy or rocky biome, with little precipitation
and little plant life
21
Desert

• Moisture Sporadic, highly localized lt20cm
  precip/year
• Temperature Great Daily range, avg 66F-76F
• Vegetation Sparse trees and shrubs
• Animals small mammals, birds, reptiles

22
Desert Vegetation Profile
23
Midlatitude Grasslands
A biome where grasses, not trees, are the main
plant life. Prairies are one kind of grassland
region.
24
Midlatitude Grassland

• Moisture tall-grass, which are humid and very
  wet, and short-grass, which are dry
• Temperature-40 F in winter, and in the summer
  it can be as high 70 F
• Vegetation large, rolling terrains of grasses,
  flowers and herbs.
• Animalslarge and small mammals, birds, insects

25
Midlatitude Grassland Vegetation Profile
26
Savanna
A savanna is a rolling grassland scattered with
shrubs and isolated trees, which can be found
between a tropical rainforest and desert biome.
27
Savanna

• Moisture wet season, dry season
• Temperature hot
• Vegetation tall grasses, shrubs, trees
• Animals large mammals, birds, reptiles

28
Savanna Vegetation Profile
29
Tundra
A cold biome of the far north the ground is
frozen even in summer
30
Tundra

• Moisture dry season, wet season
• Temperature cold all year
• Vegetation shrubs, grasses, mosses
• Animals birds, insects, mammals

Biome Report1-2 pages, Due Tuesday

• Students are asked to build a three-dimensional
  model of a biome in a box (no larger than a
  shoebox) using everyday materials. Included in
  the model should be representative examples of
  flora and fauna, and it should show the terrain
  (mountainous, flat, shoreline, etc.). The inside
  walls of the box should be decorated (painted,
  collaged with photos, etc.) . Taped onto one side
  of the box should be a written description of all
  of the characteristics of the biome (elevation,
  precipitation levels, temperature , flora, fauna,
  animals etc). Taped onto the other side of the
  box is a world map indicating (by color, outline,
  etc.) the locations of this biome.
