1 CH. 15 THE BIOSPHERE 1

2 15.1 BIOSPHERE Part of Earth where life exists All of Earth s ecosystems Biota all living things in biosphere Abiotic factors NOT included Ex: water, air, rocks 2

3 EARTH S SYSTEMS 1) Biosphere 2) Hydrosphere water, ice, water vapor 3) Atmosphere the air around earth 4) Geosphere features of surface Continents, rocks, sea floor, all below surface 3

4 ECOSYSTEMS ARE LINKED Change in one sphere affects others Ex: What could result if plants are removed from a riverbank? How does this affect the other spheres? 4

5 GAIA HYPOTHESIS Proposed by James Lovelock United Kingdom Considers Earth itself a kind of living organism Recognizes connections and feedback loops between biotic and abiotic factors More CO 2 = more plants More plants = more O 2 More O 2 = few plants Cycle continues Earth is NOT a thinking being! 5

6 15.2 CLIMATE Prevailing weather of a region Includes: Ave temp Ave precipitation Relative humidity Seasonal variations 6

7 MICROCLIMATE Small, specific climate within a larger climate Very important to life Ex: hole in rotting log Grassy meadow Top of tree San Francisco 7

8 3 CLIMATE ZONES Ave temp and precipitation determine 1) polar 2) tropical 3) temperate 8

9 WHAT DETERMINES CLIMATE? Sun Air and water movement Landmasses 9

10 SUNLIGHT Rays most intense (thus hottest) where strikes directly Region near equator = most sun Polar regions = least sun Rays strike at lower angle/less intense Earth s axis More tilted away from sun = less light = colder 10

11 AIR AND WATER Movement caused by Sun when it heats Earth Warm = less dense Rises Cools as it rises; releases moisture Currents movement in water Connected to: Water temp Air movement Earth s rotation Salt levels 11

12 LANDMASSES Land heats up and cools more quickly that water Coastal areas = smaller changes in temperature Water evaporates faster from water than land Coastal areas = more humid and more precipitation Mountains air cools as it rises Side facing wind = wet Downside of wind = rain shadow area of decreased precipitation 12

13 ADAPTATIONS Organisms adapt to survive Ex: Frog p. 433 What enables it to survive so well? Polar bear? 13

14 15.3 BIOMES Characterized by climate and plants 6 major biomes Broad Can be divided more specifically Ice caps and mountains are NOT biomes 14

15 1) TROPICAL RAIN FOREST Warm temp Lots of precipitation Thick forests Limiting factor = Sunlight Little reaches ground <1% Infertile soil Canopy tops of trees Many animals Epiphyte plant that grows above ground (ex: on trees) 15

16 2) GRASSLAND 2 Types A)Tropical (Savannas) Africa, S. America, Australia Grasses 3-7 ft. tall Some shrubs Limiting factor = rainfall Rainy and dry season Hoofed animals dominate biome 16

17 2) GRASSLAND B)Temperate S. Africa, E. Europe, N. America rain/snow per year Most in spring/early summer Dry and warm summers Many animals live below ground Fires are common Some seeds need fire to germinate 17

18 3) DESERT Very dry (arid) <10 precip per year Many nocturnal animals Plants = cacti-like or have deep roots 4 types 18

19 3) DESERT A) Hot >100 F Precip falls as rain B) Semiarid Temps rarely exceed 100 F C)Coastal F D) Cold Precip mostly snow 19

20 4) TEMPERATE Distinguishable seasons 2 Types: A) Deciduous forest Trees drop leaves/go dormant precip Spread evenly thru year Hot summer/cold winter 20

21 4) TEMPERATE B) Rain forest - Long wet season/short, dry summer >98 precip Evergreens dominate Coniferous retain needles all year 21

22 5) TAIGA = Boreal forest Cooler climates Cold, long winter Short, humid summers precip per year Coniferous forest dominant 22

23 6) TUNDRA Subzero temps North latitudes Long winter < 5 precip Permafrost permanently frozen ground Barren Few plants and animals 23

24 MINOR BIOMES Ex: Chaparral (Mediterranean shrubland) Hot, dry summer Cool, moist winter Along S. CA coast rain Read p

25 POLAR ICE CAPS No soil No plant community Permanently frozen NOT a biome Ex: Antarctica, parts of Greenland, N. Pole 25

26 MOUNTAINS NOT a biome Rich biodiversity As elevation increases, life characteristics change Represents various biomes Ex: grassland at bottom Deciduous forest in middle Tundra at top 26

27 15.4 MARINE ECOSYSTEMS Oceans Separated into zones Use following abiotic conditions: Sunlight Temp Salinity Turbidity (murkiness) Depth Water Chemistry 27

28 OCEAN ZONES Dif systems used: 1) separates pelagic zone (open sea)from benthic zone (floor) 2) presence of light Photic zone vs. aphotic zone (depths) 3) 4 zones made using: Distance from shore Water depth 28

29 SYSTEM #3: 4 MAJOR ZONES 1) Intertidal land bw high and low tide Ex: Beach and tidal pools Variety of conditions Organisms must adapt 2)Neritic from intertidal to continental shelf Depth = few cm to >200m 29

30 SYSTEM #3: 4 MAJOR ZONES 3) Bathyal edge of neritic to base of continental shelf Greek = deep 200m to 2000m Turbid; lots of silt High pressure Burrowing animals thrive 30

31 SYSTEM #3: 4 MAJOR ZONES 4) Abyssal below 2000m Greek = bottomless Complete darkness Deep sea vents Support life Chemosynthetic organisms Base of food web Strange organisms Some make own light 31

32 NERITIC ZONE LIFE < 1/10 th of ocean 40x more biomass than rest of ocean Plankton tiny, free-floating organisms Includes: Zooplankton Animals Phytoplankton - photosynthetic protists Ex: algae Base of food chain Estimate produce up to 70% of all oxygen 32

33 COASTAL HABITATS Shallow waters of neritic zone Coral reefs tropical climate Mutualistic relationship w algae Algae = nutrients for reef Reef = home for algae Reef = mostly dead skeletons Support lots of life Over 400 dif species of coral Delicate Sensitive to pollution, temperature Artificial reefs Ex: shipwrecks 33

34 COASTAL HABITATS Kelp forests cold, nutrient-rich water = seaweed forests Grow up to ~100 ft High productivity Habitat: Ex: small invertebrates Sea lions Underwater Kelp Forests - YouTube [360p].mp4 34

35 15.5 FRESHWATER Estuary where river flows into ocean Salt and freshwater Partially enclosed Nutrient rich Tide changes water levels Highly productive ecosystem Comparable to rain forest and coral reef Contain lots of decomposers Home to many endangered species 35

36 ESTUARIES 75% of fish we eat depend on nurseries of the sea Fish spawn Young mature Birds migrate/layover here Threats: Humans Development Pollution Erosion Up to 80% have been lost in U.S. What's An Estuary_ Now You Know. - YouTube [360p].mp4 36

37 FRESHWATER Moving and standing water Wetlands standing water Very productive Help maintain clean water Filters and renews underground supply Ex: Bogs, marshes, swamps ID by plant communities 37

38 FRESHWATER Factors that affect life here ph Oxygen levels Water temp Water flow How would a tadpole in a pond differ from that in a fast moving river? 38

39 WATERSHED Region of land that drains into a body of water Where lakes, streams, and ponds originate 39

40 3 FRESHWATER ZONES Lakes and ponds Some may not have all 1) Littoral similar to intertidal Between high and low water marks on shoreline Well-lit Warm Shallow Diverse organisms: Invertebrates Water plants 40

41 3 FRESHWATER ZONES 2) Limnetic (pelagic) open water farther from shore Lots of plankton 3) Benthic - bottom Less sunlight Many decomposers 41

42 WATER TURN OVER Water differs in temp layers separated by thin zone called thermocline Water most dense at 39 F When reaches this temp, it sinks below other water whether warmer or colder Moving all year Mixes nutrients from bottom Planet Earth - Fresh Water HD - YouTube [360p].mp4 2:45 42
