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

5. Tundra

6. Tundra 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

8. Taiga

9. Taiga 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

11. Desert

12. Desert 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

14. Savanna

15. Savanna
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

17. Tropical rainforest

18. Tropical rainforest
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

20. Temperate forest

21. Temperate forest
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

23. mountains

24. mountains 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

26. Grasslands

27. Grasslands 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. Freshwater Streams & Rivers: Ponds & Lakes:
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. Estuaries
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. marine 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
