TundraBiotic Factors
Plants
Mosses, dwarf shrubs, lichen, grasses
Animals
Musk oxen, wolves, caribou
Abiotic Factors
Permafrost, soil, little
rainfall, cold temperatures
Adaptations
Low to the ground to stay warm.
Grow in clumps for warmth
Red or dark color to absorb heat
• Caribou
reindeer
TundraAnimals
Caribou, reindeer, arctic fox, arctic hare, timber wolf, musk oxen, water birds, lemmings, voles
Tundra:Polar Tundra – near the
North and South Poles
Alpine Tundra – found at the top of all mountains; above the tree line
Adaptations
Thick fat (blubber), brown color (summer) and white (winter), thick fur or feathers, compact bodies, strong hooves, migration
Rainforest
Emergent___-tallest trees___
Canopy-upper branches & leaves
Understory_-__shrubs______
Floor__-__lichens, mosses__
Adaptations
Drip tips
Plants grow on trees
Plants that hold water
Roots form buttresses
Smooth bark

Abiotic FactorsLittle light reaches the groundYearly rainfall – 400 cm(157.5 in)Average Temp
Day - 93 F ; Night – 68 FSoil is thin and poor in nutrients
Adaptations
-insects on the forest floor are decomposers.
-Large beak for eating nuts and fruits
-Covered with moss and beetles
-Deadly poison-brightly colored to warn others
Temperate Deciduous Forest
Temperate Deciduous Forest Abiotic FactorsMild temperatures average – summer 82 F winter – 45 FPlenty of rain
Biotic Factors AnimalsBearsSnakesBirdsRabbitsDeersquirrels PlantsFerns, mosses, flowering plantsTrees – change colors in the fall and
shed their leaves in the fall
Adaptations
Hibernate in the winter
Hibernate in the winter
Migrate for the winter
Store food for winter
Coniferous Forest
Coniferous ForestCone bearing trees (Evergreen)
Biotic Factors AnimalsDeer, Moose, Porcupines, Squirrels,
Elk,Wolves, Insects PlantsCone bearing trees (Evergreen)Pine, Fir, SpruceFew plants live here due to low
amounts of sunlight
Abiotic FactorsCold temperaturesModerate rainfallSnow usually covers ground in winterLittle sunlight reaches ground
Adaptations Most of the animals hibernate in the winter
Birds migrate to the south for the winter
GrasslandPlants Adaptations
Soft stems that bend in wind or short stems to give support
Extensive roots to keep animals from uprooting them
Shrubs have extensive roots
-colorful blooms to attract insects for pollination
½ the plants are grasses
Tall grasses:iron weed, wheat grass
Short grasses: alfalfa, ragweed
Shrubs
Wildebeest Tapir
GrasslandBiotic Factors
AnimalsTigers, giraffes,
ostrich, antelope, wildebeest,
Prairie dogs, buffalo or bison,
Abiotic FactorsCan be very windyDroughts in the summerBlizzards in the winter
Adaptations
different animals eat from different parts of the plant.
Stripes or spots for camouflage
Paws to burrow
Flat topped teeth
nocturnal
Cholla cactus
yucca
Joshua Tree
DesertPlants
Cactus
Joshua tree
Tumble weed
No large trees
Adaptations
-have thorns, spines, or thin, leathery leaves
-store water in stems, roots, or leaves
-extensive (long) root systems
Antelope jackrabbit
Bark Scorpion
Gila Monster
pack rat with cactus
fennec fox
Western Coral Snake
DesertAnimals
Camels-close nostrils, long eyelashes
Fennec fox
Pack rats
Reptiles
Few birds
Desert toads-stay underground until rain
AdaptationsNocturnal (out at
night)Small body with long
legs for coolingLarge earsCold bloodedBuild underground
tunnelsLight in color to
reflect lightEstivation-sleep
during hot months
Deep-rooted chaparral shrub covers the southern face of
the mountains.
The yellow pine forest is a mixture of oak, fir, cedar, and pine trees.
MountainPlants
Chaparral- deep rooted shrub
Evergreen trees, herbs, ferns
Adaptations
Short stems for support
Wide root systems
Waxy leaves to conserve water
Rocky Mountain Goats
Big Horn Ram
Takin
goat antelopes
MountainAnimals
mountain goats,
Big horn sheep or rams,
takin, goat antelopes
Adaptations
Cloven (split) hooves for balance
Soft pads in the center of the hard hooves act as shock absorbers.
Large lungs and hearts to get oxygen from thin mountain air
Aquatic BiomesMarine Biome and Freshwater Biome
Marine BiomeIncludes Large bodies of
salty water• Oceans• Coral Reefs• Estuaries
Freshwater BiomeIncludes most:• Lakes• Rivers• Streams• Brooks, • Swamps• Ponds
Marine Biome
Marine BiomeThe largest biome
Biotic Factors AnimalsWhales, Sea otters, fish, mollusks,Crustaceans
Abiotic FactorsTemperture – top of the ocean is warmer and gets colder as you decendSunlight – more sunlight at the top portion and you decend it gets darker
