Transcript

  • 1. ECOLOGICAL SYSTEM
  • 2. CELL PHONES FUNCTION Why do we have a Cell phone system? Structures Behavior Contribution to Function What part is What does the How does the part help contribute to its involved? part do? function?Interconnection: Describe how the different structures work together to perform its function/s.________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
  • 3. Systems have BFS…. IC• Behavior = Role (role of each part)• Function = Purpose (purpose of the whole system)• Structure = Parts• Interconnection – there are links between parts• Changes – If a part fails to perform, it will affect the whole system
  • 4. 4 Laws of Ecology1- Everything is connected to everything else.2- Everything must go somewhere.3- Nature knows best.4- There is no such thing as a free lunch The Earth as a Closed SystemHEAT Energy, flows, matter cycles
  • 5. 4 Laws of Ecology1- Everything is connected to everything else.2- Everything must go somewhere.3- Nature knows best.4- There is no such thing as a free lunch Is the E-column a Closed System? Explain.HEAT Energy, flows, matter cycles
  • 6. The EcosystemAll the living and nonliving things thatinteract in a particular area make upan ecosystem. Organisms live in a specific place within an ecosystem. An organism obtains food, water, shelter, and other things it needs to live, grow, and reproduce from its surroundings.
  • 7. The place where an organism lives and that provides the things theorganism needs is called its habitat. Terrestrial Habitats Freshwater Habitats Image source: http://www.bbc.co.uk/nature/habitats Marine Habitats
  • 8. A species is a group of organismsthat are physically similar andcan reproduce with each other toproduce fertile offspring.All the members of one speciesin a particular area are referredto as a population.All the different populations thatlive together in an area make upa community.
  • 9. BIOTIC AND ABIOTIC FACTORS http://www.youtube.com/watch?v=y-wpbhnom70 http://www.youtube.com/watch?v=rNfmew9C508 Learn more…. Biotic and Abiotic Factors
  • 10. The living parts of an ecosystem are called biotic factors.The nonliving parts of anecosystem are called abioticfactors.Abiotic factors includewater, sunlight, oxygen, temperature, and soil. Image source : http://en.wikinoticia.com/
  • 11. Level of Acidity (pH)
  • 12. The biotic community and abiotic factors together form anecosystem. Image source: exploringnature.org The study of how living things interact with each other and with their environment is called ecology.
  • 13. Group Brainstorm: Create a list of biotic and abiotic factors for your assigned chamber. Share your list to your group mates. Discuss and make revisions in your list. Make a list of 5 important things you need to do to sustain your E-column. Think about what each chamber contributes to the other chambers.
  • 14. Make a list of 5 important things you need to do to sustain your E-column. What will happen if these are not followed? Think about what each chamber contributes to the other chambers. 5 Important Things Negative Effects
