1 Biomes of Earth Unit 1 S7L4.e. EQ: What are the 6 major biomes on the Earth?


3 To understand a world biome, you need to know: What the climate of the region is like including temperature & precipitation patterns. Where each biome is found and what its geography is like. The types of plants found in the biome. The types of animals found in the biome.

4 Tundra


6 little precipitation & very windy. Permafrost – frozen soil mostly northern hemisphere few trees, has mosses, grasses, shrubs extremely cold (winter = low as -50 ° F, summer = high as 45 ° F) caribou, Arctic hares, insect-eating birds, wolves, foxes, bears and deer

7 Taiga


9  Coniferous trees (cones & needles), firs, spruce, hemlock  Very cold, lots of snow. Summers are rainy and warm enough to melt the snow.  Temps range from 11 °F in winter to 75 °F in summer  Seed eating animals – squirrels, insects, birds (finches & chickadees)  Herbivores – hares, moose, beavers  Carnivores – wolves, bears, lynxes

10 Desert


12  Temp 68 to 120 ° F  Less than 25 centimeters of rain per year  very little rainfall and/or concentrated rainfall in short periods between long rainless periods  Plants include: Cactus, Prickly Pears, and Brittle Bush  Animals include: insects, arachnids, reptiles, and birds, and Horned Vipers

13 Savanna


15  tropical grasslands found in a wide band on either side of the equator on the edges of tropical rainforests  a very long dry season (winter), and a very wet season (summer)  68° to 86° F  120 centimeters of rain each year  Herbivores - Elephant, bison, antelopes, zebras, rhinoceros, giraffes, kangaroos.  Plants include shrubs and small trees, grasses

16 Tropical rainforest


18  325 to 1650 centimeters (50 – 260 inches) of rain per year  rarely gets higher than 93 °F or drops below 68 °F  Almost all rain forests lie near the equator  Bengal Bamboo, Bougainvillea, Curare, Coconut Tree, Durian, Jambu  Africa Forest Elephant, Bengal Tiger, Chimpanzee, Common Palm Civet or Musang, Dawn Bat, Golden Lion Tamarin, Harpy Eagle  that more than half of all the world's plant and animal species live in tropical rain forests. Tropical rainforests produce 40% of Earth's oxygen

19 Temperate forest


21  Located in the northwestern coast of the United States  Receives more than 300 centimeters of rain a year  Huge trees including cedars, redwoods, and Douglas firs  Animals include mule deer, bald eagle, fox, black bear  Moderate temperatures – average 75 °F (24 °C)

22 mountains


24  Found all around the world  Altitude of about 10,000 feet or more  Series of biomes as you go up. Base = grasslands Midway = forest Top = Tundra  Summer temperature range between 10 °F to 50 °F  Plants include: grasses, dwarf trees, small-leafed shrubs  Animals include: mountain goats, sheep, elk, beetles, grasshoppers

25 Grasslands


27  Winter low as -40° F, summer high 70° F  two seasons: growing season and dormant season  25 to 75 centimeters of rain each year  Buffalo Grass, Sunflower, Crazy Weed, Asters, Blazing Stars, Coneflowers  Coyotes, Eagles, Bobcats, the Gray Wolf, Wild Turkey, Fly Catcher, Canadian Geese, Crickets

28 Aquatic Biomes of Earth Unit 1 S7L4.e. EQ: What are the 3 major aquatic biomes on the Earth?

29 Freshwater

30  Streams & Rivers:  Streams - Animals are adapted to strong currents (insects & small animals have hooks or suckers to cling to rocks). Trout live here but few plants & algae so leaves and seeds provide food.  Rivers – Cloudy with soil, Plants take root, frogs, fish.  Ponds & Lakes:  Standing or still fresh water. Lakes are larger & deeper than ponds.  Ponds – plants can grow, catfish  Lakes – plants & algae float, dragonflies, turtles, snails, frogs, fish

31 Estuaries

32  Found where the fresh water of a river meets the salt water of the ocean, calm waters  Algae, marsh grasses  Crabs, worms, clams, and fish

33 marine


35  Intertidal Zone - Neritic Zone - Open Ocean  All marine ecosystems are based on saltwater  Intertidal Zone: shoreline, animals (barnacles, sea stars, clams, & crabs)  Neritic Zone: photosynthesis can occur. Rich in living things, large schools of fish (sardines), algae, coral reefs  Oceanic Zone: surface zone w/algae & Deep zone w/giant squids  Benthic Zone: ocean floor, organisms include bacteria, works, sea urchins
