									introduction
Biomes of the World
                Definition
• The Earth has many different environments,
  varying in temperature, moisture, light, and
  many other factors. Each of these habitats
  has distinct life forms living in it, forming
  complex communities of interdependent
  organisms. A complex community of plants
  and animals in a region and a climate is
  called a biome.
There are 8 Major Biomes:
        1. Tundra
        2. Taiga (Boreal Forest)
        3. Temperate Forest
        4. Tropical Rain Forest
        5. Grasslands
             Savanna and Temperate
        6. Desert
        7. Marine:
             Ocean and Freshwater
Biomes of the World
Tundra
-”Top of the World”

-Climate is cold
-ground is frozen, known as permafrost
-Average temperature is 10-20’F
-Little water
-Every animal must adapt to the cold
-During the brief summers, the ground thaws and plants grow
Biomes of the World
Herbivorous mammals:
         lemmings, voles, caribou,
        arctic hares and squirrels
Carnivorous mammals:
                                        Tundra
       arctic foxes, wolves, and
       polar bears
Migratory birds: ravens, snow
      buntings, falcons, loons,
      ravens, sandpipers, terns,
      snow birds, and various
     species of gulls
Insects: mosquitoes, flies,
     moths, grasshoppers,
     black flies and arctic
     bumble bees
Fish: cod, flatfish, salmon, and
      trout
Plants: lichen, cushion plants, berry
         bushes, cotton grass, dark
         red leaves
-   Largest biome in the world.
-Mostly Canada and northern Europe and Asia.

    By Andy Marlin are Jimmy Willis
-During summer, thereand a lot of insects,
     therefore, birds migrate to feed.
-Forests are prone to wildfires, so some trees
     adapt by growing thick bark.

Biomes of the World
•   Many different types of vegetation exist in the Tropical Forest.
    Some trees are 25-50 meters tall. Some plants include the
    jungle tree, flowers, orchids, ferns, mosses, palms, bromeliads,
    and vines. There are many plants still unknown, and some
    plants have cures for diseases such as malaria, cancer, and
    aids. The canopy that the plants form shade the forest floor
    and protect the animals.
Fifty percent of the worlds animal population
is in the Tropical Forest. Some of these
animals include primates, snakes, lizards,
birds, insects, frogs, cats, bats, small
mammals, and moths.

         Review Questions
1. What are the 8 Biomes?
2. What are the two most unique
  characteristics about the different Biomes?
3. How does the type of flora depend on the
  types of fauna?
4. What are some similar human impacts on
  each Biome?
5. How can we protect our Biome?
