WARM UP 1 1018 Describe the difference between
WARM UP � 1. 10/18 Describe the difference between the Deciduous Forest and the Coniferous Forest Biomes. � 2. How are the TUNDRA and DESERT similar? How are they different?
TODAY’S AGENDA… � 1. Put ANSWERS INTO I-RESPOND…. (I will call you up to do so. ) Not everyone can use an i-respond at once. � 2. While we are waiting, you should be working on the AQUATIC BIOMES WORKSHEET if needed. It needs to be handed in when you are finished. � 3. BIOME PASSPORT FILL IN– We will work as a class to fill in any gaps in your passport books.
BIOME PASSPORT Please take careful notes!! You will use the Biome books for your upcoming Biome project! AND for the BIOME EXAM on 10/23 & 10/24 IF YOU RUN OUT OF SPACE, PUT THE INFORMATION IN YOUR IAN!

DECIDUOUS FOREST (Temperate Forest) � Temperature: Summer: 28 Deg. C (82 F) Winter: 6 Deg. C (43 F) Rainfall: 75 -125 cm (29. 5 -49 in) Soil: Fertile (Allows many different types of trees to grow) Common Plants(Flora): Treesoak, beech, maple, elm, willow Flowering herbs
Deciduous continued… � Plant Adaptations: Leaves fall off the trees in order to conserve water � Common Herbivores: ◦ Possums, rabbits, squirrels, raccoons, deer ◦ Common Carnivores: �Bears, snakes, woodpeckers � Animal Adaptations: ◦ Some animals hibernate in the winter ◦ Animals gather food to store to make it through the winter ◦ Many grow thicker coats to keep warm in winter and shed in summer
Endangered Species of Deciduous Forests… � American Bald Eagle � American Black Bear � Duckbill Platypus
Description of the Biome: 4 Seasons (summer, winter, spring, fall) Found in the eastern half of North America, middle of Europe, Asia, New Zealand Australia Losing land due to farms and humans building (some areas protected)
Coniferous Forest (Taiga or Boreal Forest) � Temperature: Summer: 14 Deg C(57 F) Winter: -10 Deg. C (14 F) Rainfall: 35 -75 cm (14 -29. 5 in) Soil: thin, nutrient poor, and acidic Common Plants (Flora): Conifer trees (have seeds, pinecones) Pine, Fir, Spruce
Coniferous Continued… � Plant Adaptations: ◦ Conifer trees have a waxy coating to prevent them from drying out, and protects them from cold winters ◦ Trees stay green all year round– called evergreen trees � Common Animals: ◦ Woodpeckers, hawks, moose, bear, weasel, lynx, fox, deer, chipmunks, bats ◦ Animal Adaptations: �Hibernation �Migration �Storage �Body and Color Adaptation (thicker coats in winter, different colors)

Description of the Coniferous Biome… � The Coniferous Forest has cold, long, snowy winters, and warm, humid summers; welldefined seasons, at least four to six frost-free months.
Tropical Rainforest � Temperature: Daytime: 34 Deg C (93 F) Nighttime: 20 Deg C (68 F) (Doesn’t have distinguished seasons) � Rainfall: � Soil: � up to 400 cm per year (157. 5 in) Nutrient poor, acidic, topsoil is only 2 inches Where rainforests are located: -Central America -Africa -Indo-Malaysia India -Southeast Asia, - New Guinea and Australia.
Tropical Rainforest Continued… � Common animals: ◦ Jaguar, many tropical birds, small mammals, Insects make up the largest single group of animals � Animal Adaptations:
Common Plants (Flora): Highly diverse plant life, has more kinds of trees than any other area in the world, Only covers 6% of the Earth’s surface, but provides 20% of our oxygen. � Plant Adaptations: ◦ plants shed water off their leaves quickly so the branches don't get weighed down and break To absorb as much sunlight as possible, leaves are very large
Endangered Animals in Tropical Rainforests: � Jaguars � Orangutans � Macaws � Sloths
Savannas (Tropical Grasslands) Contain the greatest number of grazing animals on Earth. Location: Found in the tropics…near equator Amount of precipitation supports tall grasses but only occasional trees. The word savanna stems from an Amerind term for plains http: //www. runet. edu/~swoodwar/CLASSES/GEOG 235/biomes/savanna. html

Polar Ecosystems Can be considered marine ecosystems since the base of food chain is phytoplankton www. awi-bremerhaven. de www. defenders. org
Arctic vs. Antarctic Relatively Penguins live here— shallow, lots of only continent not nutrients for used by humans large variety of (exc. Research) animals in food web, People, seals and polar bears found nmml. afsc. noaa. gov here.
Threats to the Polar Ecosystems Reserves of minerals draw humans to these fragile ecosystems. The main threat to wildlife has been the increase in tourism—garbage left behind newt. phys. unsw. edu. a u
MARINE BIOMES… � Oceans � Photic Zone– Portion of marine biome that is shallow enough to penetrate sunlight � (coastlines-shore, beaches, mudflats) � Aphotic Zone– Deeper Waters that do not receive sunlight. (Deep, least explored oceans) � Phos- Light (Greek) � A- Without (Greek)
Marine Life � Largest amounts of biomass (living materials) though often very small � Whales, � Kelp, seals, sea otters, sea cows algea, sea grass
Estuary � Bay, sound, fjord, salt marshes, wetlands � Freshwater mixes with salt water (some land) � Brackish Water (more salt than freshwater; but less than marine) � Salinity ranges ◦ Amount of freshwater vs. Saltwater ◦ Tides ◦ Biodiversity
Estuary Life � Eelgrass, smooth cordgrass, sea lavender � Shiner Perch, Starry Flounder Orange Striped Jellyfish, Purple Shore Crab, Scallop � Predators– � Decay cranes and other birds of dead organisms is quick, nutrients recycled through food web.
Freshwater Biomes � Major abiotic factors: temperature and light � Not enough sunlight penetrates to bottom to support photosynthesis ◦ Few aquatic plants or algea grow ◦ Population density lower ◦ Bacteria break down dead organisms and recycle nutrients
Freshwater Life � Concentric � Cattails, bands or clusters of species sedges � Tadpoles, aquatic insects, turtles, worms, crayfish, beetles, dragonflies, minnows, bluegill, carp.
