  1. ORGANIZATION IN THE BIOSPHERE

  2. ORGANIZATION IN THE BIOSPHERE • WHAT DOES BIOLOGY MEAN? • THE STUDY OF LIVING THINGS • WE’VE LOOKED AT THE BUILDING BLOCKS OF LIVING THINGS… • BUT WHERE DO WE FIND ALL LIVING THINGS? • DO WE FIND THEM IN SPACE? • IN LAVA? • WHY NOT??

  3. ORGANIZATION IN THE BIOSPHERE LIVING THINGS, AS WE KNOW THEM, ARE CONFINED TO A SPECIFIC AREA OF EARTH THAT WE CALL… THE BIOSPHERE!!

  4. ORGANIZATION IN THE BIOSPHERE • THE BIOSPHERE IS DEFINED AS: • THE AREA ON EARTH WHERE ALL LIVING THINGS EXIST • THE BIOSPHERE IS COMPOSED OF: • LIVING THINGS (THE LIVING ENVIRONMENT) • EXAMPLES? • NON-LIVING THINGS (THE PHYSICAL ENVIRONMENT) • EXAMPLES??

  5. ORGANIZATION IN THE BIOSPHERE • THE PHYSICAL ENVIRONMENT (EARTH SCIENCE ANYONE??) • EXAMPLES INCLUDE

  6. ORGANIZATION IN THE BIOSPHERE • THE LIVING ENVIRONMENT • WITH SO MANY DIFFERENT LIVING THINGS, WE NEED TO ORGANIZE THEM TO BE ABLE TO EFFECTIVELY STUDY THEM… • ANYONE REMEMBER OUR LEVELS OF ORGANIZATION…I.E. HIERARCHY OF LIFE • SPECIES (ORGANISM)  POPULATION  COMMUNITY  ECOSYSTEM  BIOME  BIOSPHERE

  7. ORGANIZATION IN THE BIOSPHERE

  8. ORGANIZATION IN THE BIOSPHERE • ECOLOGY • THE STUDY OF LIVING THINGS AND THEIR INTERACTIONS WITH EACH OTHER (LIVING ENVIRONMENT) AND THE ENVIRONMENT (PHYSICAL)

  9. ORGANIZATION IN THE BIOSPHERE • HOW DO LIVING THINGS INTERACT WITH OTHER LIVING THINGS? • ECOLOGY OF POPULATIONS AND ECOSYSTEMS • POPULATION DYNAMICS • CARRYING CAPACITY • AUTOTROPHS & HETEROTROPHS • SYMBIOTIC RELATIONSHIPS • PARASITISM • COMMENSALISM • MUTUALISM • PREDATOR/PREY

  10. ORGANIZATION IN THE BIOSPHERE • OTHER INTERACTIONS INCLUDE • COMPETITION • INTERSPECIFIC VS INTRASPECIFIC • FOR WHAT DO LIVING THINGS HAVE TO COMPETE? • RESOURCES (EXAMPLES?) • HABITAT VS. NICHE?

  11. ORGANIZATION IN THE BIOSPHERE • ORGANISMS CAN TAKE ON THE FOLLOWING ROLES IN AN ECOSYSTEM • PRODUCER  DEFINITION? • CONSUMER  DEFINITION? • DECOMPOSER  DEFINITION? • WE USE FOOD CHAINS AND FOOD WEBS TO ORGANIZE RELATIONSHIPS BETWEEN ORGANISMS WITH THESE ROLES

  12. ORGANIZATION IN THE BIOSPHERE

  13. ORGANIZATION IN THE BIOSPHERE WHEN WE STUDY FOOD CHAINS AND WEBS, WE FIND A SPECIFIC RELATIONSHIP TO AN ORGANISMS ROLE (PRODUCER VS CONSUMER) AND ITS TOTAL NUMBER WE REPRESENT THIS RELATIONSHIP IN A PYRAMID AND CALL IT A:

  14. ORGANIZATION IN THE BIOSPHERE • PYRAMID OF BIOMASS OR PYRAMID OF ENERGY • PRODUCER • CONSUMER • HERBIVORE • CARNIVORE • OMNIVORE

  15. ORGANIZATION IN THE BIOSPHERE • WHERE ARE THE DECOMPOSERS IN ALL OF THIS? • THEY ARE EVERYWHERE, AT EVERY LEVEL… • WHY? WHAT DO DECOMPOSERS DO? • RECYCLE ORGANIC MATTER • IS ORGANIC MATTER THE ONLY THING RECYCLED IN ECOSYSTEMS? • WHAT ELSE GETS RECYCLED? • WATER, OXYGEN, CARBON DIOXIDE, NITROGEN

  16. ORGANIZATION IN THE BIOSPHERE

  17. ORGANIZATION IN THE BIOSPHERE • DO ECOSYSTEMS CHANGE? • ECOLOGICAL SUCCESSION • THE PROCESS BY WHICH AN EXISTING COMMUNITY IS SLOWLY REPLACED BY ANOTHER COMMUNITY • KEY TERMS • DOMINANT SPECIES • CLIMAX COMMUNITY • PRIMARY SUCCESSION • *PIONEER ORGANISMS • SECONDARY SUCCESSION

  18. ORGANIZATION IN THE BIOSPHERE • DO ALL ECOSYSTEMS LOOK THE SAME? • WHY NOT? • WHAT DO THEY LOOK LIKE? • A SLIDESHOW OF BIOMES NEXT 
