The document discusses the different spheres that make up the Earth's structure and the levels of organization for living things. It defines key terms like biosphere, ecosystem, individual, population, community, species, organism, biotic and abiotic factors. The main levels of organization from smallest to largest are individual, population, and community. An ecosystem is defined as an area where organisms interact with living and nonliving environmental factors.
Sorting Out Life
- 1. Bell Ringer Quickly and quietly… Get out a piece of paper List the following words & try to explain what they mean. Individual Population Ecosystem Community Abiotic
- 2. Sorting Out Life FOSS Investigation 2 Part 1
- 3. Organize It!! Scientists need a reference system Organize all levels of life to make sense of its structure For example – the Earth is a series of “nested, interacting spheres” Lithosphere Rocky, mineral, solid layer extending to the solid area of the Earth’s mantle http://www2.cet.edu/ete/hil912/intro/spheres.html
- 4. Earth’s Layers Continued Atmosphere Thin layer of gases surrounding the Earth that extends 600 km above the surface Hydrosphere The Earth’s water component Liquid, gas, and solids including lakes, rivers, glaciers, clouds, fog, and rain http://www2.cet.edu/ete/hil912/intro/spheres.html
- 5. Earth’s Layers continued Biosphere All the living organisms contained on & around the Earth This sphere interacts with the lithosphere and can be found in the atmosphere Ecosphere All spheres listed above are included in the ecosphere A portion of the ecosphere is found in each of the previous spheres Any area of the planet that contains a living thing in it http://www2.cet.edu/ete/hil912/intro/spheres.html
- 6. VISUAL MODEL OF THE EARTH’S SPHERES http://www.classzone.com/books/earth_science/terc/content/visualizations/es0102/es0102page01.cfm?chapter_no=visualization
- 7. Ecosphere Millions of life forms in the ecosphere Specific vocabulary to identify life within it Many of the life forms called species An individual is the smallest unit of a species A population is more than one type of organism or species These populations are part of a community.
- 8. Vocabulary Terms Organism = any living thing Species = a particular group of organisms Individual = one single organism or species Population = a group of individuals or more than one individual (species or organism) Community = interacting populations in a particular area
- 9. Three Views Smallest view Individual Medium view Population Larger view Community All deal with living part of the ecosphere Biotic factors and effects The ecosphere contains biotic and abiotic factors and effects! All living and nonliving things within it.
- 10. Ecosystem Focus for our studies in this class. Piece of ecology containing biotic & abiotic factors Example Sea Aquatic organisms Fish, kelp, algae, plankton, sharks Rocks, dirt, salt found under & in sea water
- 11. Other Vocabulary Terms Ecosystem = an area where organisms interact with nonliving factors (system) Biotic = living organisms and their products Abiotic = anything that is nonliving
- 12. Ecosystem Card Sort In groups….Organize deck of ecosystem cards into groups listed on the two papers Individual, population, Undecided, Community, Ecosystem, & Abiotic Make sure that you have a reason why you place it in the category Use the Ecosystem Card Sort WS to log your info
