         Compare the different biomes.
      (A biome is a large geographic area of
           similar climate & life forms)
 Tundra: (cold desert)
  Abiotic factors: cold
temperatures, long severe
winters, permafrost
  Biotic factors: lichens,
mosses, small plants, polar
bears, musk ox, reindeer,
caribou, lemmings, arctic
hares, penguins
 Taiga:
   Abiotic: summers short and
warm, winters long and snowy,
has spongy areas called
bogs(marshes)
   Biotic: evergreen trees(cone
trees), moose, bears, lynx, elk,
porcupines, wolverines, bobcats,
birds (jays)
 Tropical Savannah:
(Grassland)
    Abiotic: warm all year long,
little rain
   Biotic:grasses, zebra, antelope,
lions, gazelles, elephants, giraffes
 Tropical rain forest:
  Abiotic: rainfall may be over
500 cm per year
    Biotic: vines, ferns, large trees,
insects, birds(parrots), monkeys,
lizards, panthers, canopy of trees,
 Deserts:
  Abiotic: sandy, less than 20 cm
of rain, hot, dry regions
   Biotic: cacti, mesquite, insects,
iguanas, gila monsters, horned
lizards, kangaroo rats, scorpions,
spiders, snakes, sagebrush, fleshy
plants, armadillos
 Marine:
  Abiotic: salt water, distribution
of life dependent on water
temperature and light
  Biotic: plankton, starfish,
whales, sharks, squid, rays
 Freshwater:
   Abiotic: lakes, ponds, rivers,
streams, contain little salt, life
distribution is dependent on
dissolved oxygen content
  Biotic: algae, catfish, carp, bass,
trout, mosses, flowering lilies,
frogs
 Tropical dry forest:
   Abiotic: warm, alternate
between wet & dry seasons
  Biotic: deciduous tall trees,
orchids, tigers, monkeys, rhino,
snakes
 Temperate grasslands:
  Abiotic: warm summers, cold
winters
  Biotic: grasses, prairie dogs,
coyotes, antelope, rabbits, prairie
chickens
 Temperate woodland/shrubland :
 Abiotic: chaparral areas, open
woodlands
  Biotic: shrubs, coyotes, mt. Lions,
bobcats, deer, rabbits, squirrels
 Temperate forest: Deciduous
forest
   Abiotic: medium amount of
rainfall, warm springs, cold winters
  Biotic: mix of evergreen &
deciduous trees(lose their leaves),
moss, ferns, deer, black bears,
raccoons, skunks
 Northwestern coniferous
forest: (cone-bearing trees)
  Abiotic: cold winters, much
snow, mild springs and summers
