1 DO NOW Grab your portfolio
What is a biome? (look in your notes if you forgot)

2 Ecosystem Biotic Abiotic Living Lived before Can be dead
Can be parts of living things Nonliving Have never lived Are not dead Are not parts of living things

3 Ecosystem All of the abiotic (nonliving) & biotic (living) factors in an area Biomes are made up of ecosystems

4 Biomes The world’s major communities
Classified according to vegetation and organisms There are different ways of classifying biomes but the common elements are climate, habitat, animal and plant adaptation, biodiversity and human activity. L to R : Tundra, Grasslands, Aquatic, Forests, Desert

5 5 Major Biome Types Tundra Grasslands Aquatic Forests Desert
Biotic & abiotic factors determine biome classification

6 Biosphere The biosphere includes all life on earth
Biodiversity is the degree of variation (differences) of life forms within a given species, ecosystem, biome or entire planet.

7 Biodiversity Why is biodiversity good? Why is biodiversity necessary?
What happens if biodiversity is decreased?

8 Biodiversity

10 Biomes

11 Tundra Climate COLD! Permafrost: a layer of permanently frozen sub soil Short cool summer: Ground soggy and wet Small and stunted plants

12 Tundra Biotic Factors Small and stunted plants Few birds Few mammals

13 Tundra Abiotic Factors
Strong winds Low Precipitation Short & Soggy Summers Long, cold dark winters

14 Tundra Abiotic Location
NORTH North America Asia Europe

15 Desert Climate DRY Many alternate between hot and cold
Organisms can tolerate extreme conditions

16 Desert Biotic Factors Cacti and other succulents
Plants with short growth cycles Predators: mountain lions, gray foxes, bobcats Herbivores: dder, antelope Bats, birds, hawks, owls, rattlesnakes, lizards

17 Desert Abiotic Factors
Low precipitation Variable temps. Soils rich in minerals Poor organic material in soil

18 Desert Location Africa Asia Middle East United States Mexico
South America Australia

19 Forest AREA DOMINATED BY TREES Tropical Dry Forests
Tropical Rain Forests Boreal Forest Temperate Forest

20 Tropical Rain Forest More species than all other biomes combined SUPER tall trees (canopy) & shorter trees

21 Tropical Rain Forest Abiotic
Hot and wet year round Thin, nutrient poor soil

22 Tropical Rain Forest Biotic
Broad leaved trees Ferns Woody vines Sloths, jaguars, anteaters, monkeys, toucans, parrots, butterflies, anaconda

23 Tropical Rain Forest Location
South & Central America, Southeast Asia, Africa, Southern Indian, Northeastern Australia

24 Tropical Dry Forest Climate
Rainfall is highly seasonal Deciduous trees

25 Tropical Dry Forest Abiotic
Generally warm year round Alternating wet & dry seasons Rich soil

26 Tropical Dry Forest Biotic
Tall, deciduous trees – dense canopy Succulents Tigers, Monkeys, elephants, rhinos, pelicans, termites, reptiles

27 Tropical Dry Forest Location
Parts of Africa, South & Central America, Mexico, India, Australia and Tropical Islands

28 Boreal Forest (Taiga) Northern Edge of Temperate Zone
Dense Evergreen Coniferous trees COLD winters Mild summers Northern Hemisphere

29 Boreal Forest Abiotic LONG cold winters Short mild summers
Moderate precipitation High Humidity Nutrient Poor Soils

30 Boreal Forest Biotic Coniferous Trees – Spruce & Fir
Some Deciduous Trees Lynx, Timberwolves, weasels, moose, small mammals, migratory birds

31 Boreal Forest Location
North America, Asia, Northern Europe

32 Temperate Forest Climate
Deciduous and Coniferous Trees Cold Winters & Warm Summers

33 Temperate Forest Abiotic
Cold to moderate winters & warm summers Year-round precipitation Fertile Soil

34 Temperate Forest Biotic
Both Deciduous & Conifers Trees, Flowers, Mosses and ferns Deer, Black Bears, Bobcats, squirrels, raccoons, skunks, songbirds

35 Temperate Forest Location
Easter United States, Southeastern Canada, Most of Europe, Parts of Japan, China and Australia

36 Tropical Savanna Climate
More seasonal rainfall than deserts, less than tropics Cover of grasses Isolated Trees Large animals

37 Tropical Savanna Abiotic
Warm Temps. Seasonal rainfall Compact Soil Frequent Fires

38 Tropical Savanna Biotic
Tall, perennial grasses, drought-tolerant and fire-resistant trees or shrubs Predators: lions, leopards, cheetahs Herbivores: elephants, giraffes, antelopes, zebras Birds: Eagles, ostriches birds, storks

39 Tropical Savanna Location
Large parts of Eastern Africa, Southern Brazil, Northern Australia

40 Temperate Grassland Mix of grasses Fertile Soil
Most converted to agriculture Periodic fires & grazing

41 Temperate Grassland Abiotic
Warm to hot summers, cold winters Moderate, seasonal precipitation Fertile soils

42 Temperate Grassland Biotic
A lot of grasses – most resistant to drought or fire Coyotes, badgers, mule deer, antelope, rabbits, prairie dogs, cattle (introduced)

43 Temperate Grassland Location
Central Asia, North America, Australia, Central Europe, South America

44 Aquatic Marine Freshwater

45 Aquatic Climate Bodies of water

46 Aquatic Abiotic Marine Freshwater Salt Water Freshwater

47 Aquatic Biotic Animals and plants that can live in water

48 Aquatic Location
