2 Tundra Biotic 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

3 Caribou reindeer

4 Tundra Animals 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

5 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

8 Rainforest Biotic Factors Animals 30,000,000 types of insects Arachnids (spiders) toucans, parrots- 3-toed sloth- Coral snake & poison arrow frog- Jaguars, gorillas, boa constrictors ½ the world’s species of plants and animals Plants Largest variety of plants Abiotic Factors Little light reaches the ground Yearly rainfall – 400 cm(157.5 in) Average Temp Day - 93 F ; Night – 68 F Soil 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

9 Temperate Deciduous Forest

10 Abiotic Factors Mild temperatures average – summer 82 F winter – 45 F Plenty of rain Biotic Factors Animals Bears Snakes Birds Rabbits Deer squirrels Plants Ferns, mosses, flowering plants Trees – change colors in the fall and shed their leaves in the fall Adaptations Hibernate in the winter Migrate for the winter Store food for winter

11 Coniferous Forest

12 Coniferous Forest Cone bearing trees (Evergreen) Biotic Factors Animals Deer, Moose, Porcupines, Squirrels, Elk,Wolves, Insects Plants Cone bearing trees (Evergreen) Pine, Fir, Spruce Few plants live here due to low amounts of sunlight Abiotic Factors Cold temperatures Moderate rainfall Snow usually covers ground in winter Little sunlight reaches ground Adaptations Most of the animals hibernate in the winter Birds migrate to the south for the winter

13

14 Grassland Plants 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

15 Wildebeest Tapir

16 Grassland Biotic Factors Animals Tigers, giraffes, ostrich, antelope, wildebeest, Prairie dogs, buffalo or bison, Abiotic Factors Can be very windy Droughts in the summer Blizzards 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

17 Cholla cactus yucca Joshua Tree

18 Desert Plants 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

19 Antelope jackrabbit Bark Scorpion Gila Monster pack rat with cactus fennec fox Western Coral Snake

20 Desert Animals Camels-close nostrils, long eyelashes Fennec fox Pack rats Reptiles Few birds Desert toads- stay underground until rain Adaptations Nocturnal (out at night) Small body with long legs for cooling Large ears Cold blooded Build underground tunnels Light in color to reflect light Estivation-sleep during hot months

21 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.

22 Mountain Plants Chaparral- deep rooted shrub Evergreen trees, herbs, ferns Adaptations Short stems for support Wide root systems Waxy leaves to conserve water

23 Rocky Mountain Goats Big Horn Ram Takin goat antelopes

24 Mountain Animals 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

25 Aquatic Biomes Marine Biome and Freshwater Biome Marine Biome Includes Large bodies of salty water Oceans Coral Reefs Estuaries Freshwater Biome Includes most: Lakes Rivers Streams Brooks, Swamps Ponds

26 Marine Biome

27 Marine Biome The largest biome Biotic Factors Animals Whales, Sea otters, fish, mollusks, Crustaceans Abiotic Factors Temperture – top of the ocean is warmer and gets colder as you decend Sunlight – more sunlight at the top portion and you decend it gets darker

28 Freshwater Biome

29 Biotic Factors Plants Algae Cattails Animals Flagellates and Wrigglers Diatoms Leeches River rats, Muskrats, Otters and Minks. Sunfish and Bass Abiotic Factors Low salt levels High oxygen levels Rocks Dirt
