1TundraBiotic FactorsPlantsMosses, dwarf shrubs, lichen, grasses AnimalsMusk oxen, wolves, caribou Abiotic FactorsPermafrost, soil, littlerainfall, cold temperaturesAdaptationsLow to the ground to stay warm.

Grow in clumps for warmth

Red or dark color to absorb heat2

Cariboureindeer3TundraAnimalsCaribou, reindeer, arctic fox, arctic hare, timber wolf, musk oxen, water birds, lemmings, voles

Tundra:Polar Tundra near the North and South PolesAlpine Tundra found at the top of all mountains; above the tree line


Thick fat (blubber), brown color (summer) and white (winter), thick fur or feathers, compact bodies, strong hooves, migration

4RainforestEmergent___-tallest trees___

Canopy-upper branches & leaves


Floor__-__lichens, mosses__

AdaptationsDrip tipsPlants grow on treesPlants that hold waterRoots form buttressesSmooth bark



7RainforestBiotic FactorsAnimals30,000,000 types of insectsArachnids (spiders)toucans, parrots-3-toed sloth-Coral snake & poison arrow frog-Jaguars, gorillas, boa constrictors the worlds species of plants and animals PlantsLargest variety of plantsAbiotic FactorsLittle light reaches the groundYearly rainfall 400 cm(157.5 in)Average Temp Day - 93 F ; Night 68 FSoil is thin and poor in nutrientsAdaptations-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

8Temperate Deciduous Forest

9Temperate 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 winterHibernate in the winterMigrate for the winter

Store food for winter

10Coniferous Forest

11Coniferous 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 winterBirds migrate to the south for the winter12



Soft stems that bend in wind or short stems to give supportExtensive roots to keep animals from uprooting themShrubs have extensive roots-colorful blooms to attract insects for pollination the plants are grassesTall grasses:iron weed, wheat grass

Short grasses: alfalfa, ragweed Shrubs



Tapir 15GrasslandBiotic FactorsAnimalsTigers, giraffes, ostrich, antelope, wildebeest,

Prairie dogs, buffalo or bison, Abiotic FactorsCan be very windyDroughts in the summerBlizzards in the winterAdaptationsdifferent animals eat from different parts of the plant.Stripes or spots for camouflagePaws to burrowFlat topped teethnocturnal16

Cholla cactus


Joshua Tree

17DesertPlantsCactusJoshua tree Tumble weedNo large treesAdaptations-have thorns, spines, or thin, leathery leaves-store water in stems, roots, or leaves-extensive (long) root systems

Camels-close nostrils, long eyelashesFennec foxPack ratsReptilesFew birdsDesert 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 months20

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.

21MountainPlantsChaparral- deep rooted shrubEvergreen trees, herbs, ferns


Short stems for supportWide root systemsWaxy leaves to conserve water


Rocky Mountain Goats

Big Horn Ram
