Why are different organisms in different places ?

• Climate
• Global air circulation
• Terrestrial regions
• Latitude
• Altitude

Desert biomesClimate

• Low precipitation
• 30 Degrees north or south High pressure
• Interiors of continents
• Leeward side of the winds
• Warm days and cool nights

Desert biomesplants

• Beat the heat and every drop counts
• Wax-coated leaves to minimize transpiration
• Deep root system or spread out root system
• Some plants produce a toxin in their root system
  to reduce the competition
• Survive in a dormant state
• Most are armed with needles

9
Desert biomesanimals

• Nocturnal
• Mostly small in size
• Thick outer covering to reduce the loss of water
• Some become dormant during extreme times of heat

10
Desert biomeshuman impacts

• Slow growth
• Irrigation - salinization
• Extraction of oil
• Four wheel drive SUV
• Storage of toxins and radioactive waste

11
Grasslands tropicalclimate

• Inland
• High average amounts of temperature and not much
  change during the year because it is in the low
  latitude region .
• Rainy period and a dry period, the rain fall is
  effected by El nino

13
Grasslands tropicalplants

• Large underground root system so they can grow
  quickly and handle the low rain fall
• Vertical leaves that further help reduce the
  amount of transpiration
• Razor-sharp leaves that will deter hunger
  herbivores

14
Grasslands tropicalanimals

• Migratory - to follow the rain
• Give birth during the rainy season
• Herbivores reduce the competition by eating at
  different levels.

15
Grasslands tropicalhuman impacts

• Reduction of nomadic pastoralist that move their
  livestock with the rainy season
• Drilling of wells
• Importing livestock will cause Desertification

16
Temperate grasslandsclimate

• 30 degrees to 60 degrees latitude
• Inland
• Change of seasons
• Cold winters and dry summers

17

18
Temperate grasslandsplants

• Grass plants
• Most fertile soils
• Dense root system to survive drought and fires
• Few trees because of the winds - leeward side of
  the mountain

19
Temperate grasslandsanimals

• Grazers bison
• Thick coats

20
Temperate grasslandshuman impact

• Cultivation and overgrazing
• Erosion

21
Taigaclimate

• Cold and little rain
• Cold air can not hold much moisture
• Cold because of the latitude
• Low amounts of sunlight during the winter

22

23
Taigaplants

• Conifer
• Waxy leaves, narrow shaped needles to keep in
  moisture
• Cone shape to shed the snow
• reduce competition because they can survive in
  acidic soil
• Shallow roots

24
Taigaanimals

• Migrate
• Hibernate
• Thick fur that is lost during summer months
• Camouflages themselves during the winter and the
  summer.

25
Taigahuman impact

• Oil pipe line
• Logging
• Slow rate of growth

26
Tropical rain forestclimate

• Low pressure
• Moisture from the ocean
• Heavy rain fall
• High temperatures throughout the year

27

28
Tropical rain forestplants

• Special adaptation for each layer of the tropical
  rain forest

29
Tropical deciduous forestclimate

• Windward side of the mountain
• High rain fall
• Moderate temperature - by an ocean

30
Tropical deciduous forestplants

• Combination of conifers and deciduous plants
• Red woods
• Douglas firs

31
Tropical deciduous foresthuman impact

• Logging
• Unique ecosystem spotted owl

32
Temperate deciduous forestclimate

• Change of seasons
• Between the 30 degrees and 50 degrees
• A clash of warm humid air and dry cold air

33

34
Temperate deciduous forestplants animals

• Lose their leaves and become dormant
• Migration hibernation thick fir ability to store
  food
• Slow metabolic rate

35
Tundraclimate

• Cold cold cold
• High latitude
• High pressure
• Loss of sunlight in the winter
• Short growing season

36

37
Tundraplants animals

• Plants that can grow without soil - lichens and
  mosses
• Short plants because of the wind
• Migration for birds and animals
• Winter camouflage
• Thick fur

38
Tundrahuman impact

• Oil
• Slow to recover
