  1. Ecological Model Describing theInter-relations ofthe Natural World. AdvancingJustice-LA.org 1AASC.UCLA.edu

  2. Native Science • Native Cultures emphasized the relationship between things in nature. • Developed basicNatural Laws • All living things are interconnected. • The natural world is in a constant state of change. • Understanding change (rather than controlling it) can give humans power while maintaining balance. AdvancingJustice-LA.org2AASC.UCLA.edu

  3. Ecology • Ecology:Study of the interactions of living organisms with one another and with their physical environment. AdvancingJustice-LA.org3AASC.UCLA.edu

  4. Organism • Organism: Defined as something that meets the criteria for a “living thing”. • Criteria: • Has genetic material • Is made up of one or more cells. • Uses energy • Reproduces • Others. AdvancingJustice-LA.org4AASC.UCLA.edu

  5. Population • Population: is a group of organisms of the same species living together in the same place and interbreeding. AdvancingJustice-LA.org5AASC.UCLA.edu

  6. Habitat • Habitat: the place where a particular population of a species lives. AdvancingJustice-LA.org6AASC.UCLA.edu

  7. Community • Community: In biology, a community is when different populations (species) live together in a habitat. AdvancingJustice-LA.org7AASC.UCLA.edu

  8. Ecosystem • Ecosystem: consists of a community and all the physical aspects of its habitat (such as soil, water, weather) • Also called: Ecological System AdvancingJustice-LA.org8AASC.UCLA.edu

  9. Biotic and Abiotic Factors • An ecosystem has factors: things that affect it. 2 types: • Biotic factors: the organisms in the habitat. • Abiotic factors: the non-living things that affect the ecosystem such as: physical structures, water, soil, etc. AdvancingJustice-LA.org9AASC.UCLA.edu

  10. Biome • Biome: is what you call a major community or communities over a large area. AdvancingJustice-LA.org10AASC.UCLA.edu

  11. Biosphere • Biosphere: is the sum of ecosystems that make up the earth. • Closed system (apart from sun & inside the earth) • Self-regulating: controls itself. AdvancingJustice-LA.org11AASC.UCLA.edu

  12. Ecological Model • Ecological Model:Is a picture we can use on how an organism is inter-related to the living and non-living things around them. AdvancingJustice-LA.org12AASC.UCLA.edu
