  • Investigation 1.C could be used as a unit project
  • Transcript of "Chapter 1 Notes And Assignments"

    1. 1. Unit A Energy and Matter Exchange in the Biosphere
    2. 2. <ul><li>Overview: The constant flow of energy and cycling of matter in the biosphere leads to a balanced or </li></ul><ul><li>steady state. This balance is achieved through various biogeochemical cycles and the processes of </li></ul><ul><li>photosynthesis and cellular respiration. </li></ul>
    3. 3. Energy Flows Through the Biosphere <ul><li>Energy from the sun flows through the planet. It may be absorbed for a time, but eventually it is reemitted back into space. </li></ul><ul><li>Energy is not EVER recycled </li></ul>
    4. 4. Photosynthesis <ul><li>This process is the only way living things are able to harness the energy from the sun. </li></ul><ul><li>The solar energy is turned into chemical energy. </li></ul>6CO 2 + 6H 2 O + light energy  C 6 H 12 O 6 + 6O 2
    5. 5. Chemosynthesis <ul><li>Chemo synthesizers found deep in the ocean where light can’t reach them, must produce their own chemical energy using raw ingredients found near geothermal vents. </li></ul><ul><li>These are the only other producers on the planet. </li></ul>http://www.teara.govt.nz/NR/rdonlyres/0312AFED-93E1-4920-B369-15D40A5ABFB9/143861/di8960enz.jpg
    6. 6. Producers <ul><li>Producers that include plants, as well as single-celled photosynthesizers such as algae and phytoplankton, are responsible for the capture of the solar energy the sustains almost all life on the planet. </li></ul>
    7. 7. http://curriculum.calstatela.edu/courses/builders/lessons/less/les5/les5gifs/kelp3.gif http://staffwww.fullcoll.edu/tmorris/elements_of_ecology/images/tree_in_field.jpg http://www.visindavefur.hi.is/myndir/phytoplankton_070305.jpg http://www.krisweb.com/krissheepscot/krisdb/html/krisweb/stream/algae.jpg
    8. 8. Consumers <ul><li>Every other living thing is unable to make its own energy and must instead consume it. </li></ul><ul><li>There are primary, secondary and tertiary consumers </li></ul>http://www.jenningsk12.net/WE/peimann/Science/FoodChains/food_chain.jpe
    9. 9. Investigation 1.B <ul><li>Pg 22 all </li></ul><ul><li>start keeping track of what you are eating for the next 3 days. </li></ul>
    10. 10. Cellular Respiration <ul><li>C 6 H 12 O 6 + 6O 2  6CO 2 + 6H 2 O </li></ul><ul><li>Once sugar is either produced or consumed, it is broken down into ATP, which is the type of energy that can be used by cells. </li></ul><ul><li>This means that cellular respiration occurs in both PLANTS AND ANIMALS </li></ul>
    11. 11. http://www.windows.ucar.edu/earth/climate/images/carboncycle_sm.jpg The Carbon Cycle
    12. 12. Laws of Thermodynamics <ul><li>Energy can’t be created or destroyed just transferred from one form to another </li></ul><ul><li>Energy always moves from high energy to low energy </li></ul><ul><li>At every energy conversion, useful energy is lost as heat </li></ul>
    13. 13. Incoming solar energy= Outgoing solar energy http://www.nasa.gov/centers/goddard/images/content/172159main_polar_radiation_budget_large.gif
    14. 14. Plants are vital for the redistribution of energy <ul><li>Only about 1% or 2% of incoming solar radiation is absorbed by producers. </li></ul><ul><li>This amount must then be used or stored otherwise it ends up back in space. </li></ul>
    15. 15. Trophic Levels <ul><li>The order of energy transfer goes from: </li></ul><ul><li>Primary producer (1 st trophic level) </li></ul><ul><li>Primary consumer (2 nd trophic level) </li></ul><ul><li>Secondary consumer (3 rd trophic level) </li></ul><ul><li>Tertiary consumer (4 th trophic level) </li></ul><ul><li>At each transfer the energy available to the next level decreases </li></ul>
    16. 16. Section 1.1 Review <ul><li>Pg 15 # 2, 3,4, 7 & 8 </li></ul>
    17. 17. Food Chains vs. Food Webs http://www.absc.usgs.gov/research/seabird_foragefish/marinehabitat/images/Food_Web3.gif http://www.kidsgeo.com/images/food-chain.jpg
    18. 18. Ecological Pyramids <ul><li>These are used to visually show the relationship between trophic levels </li></ul>
    19. 19. Pyramid of Numbers http://openlearn.open.ac.uk/file.php/1656/SK220_2_003i.jpg Some times this pyramid can be such that second trophic level can have more numbers in it than the first trophic level.
    20. 20. Pyramid of Biomass http://kentsimmons.uwinnipeg.ca/16cm05/1116/54-12-BiomassPyramids-L.gif
    21. 21. Pyramid of Energy http://kentsimmons.uwinnipeg.ca/16cm05/1116/54-11-NetProductPyramid-L.jpg This graphic shows that only 10% of the energy from one trophic level is transferred to the level above it.
    22. 22. Why isn’t there a Quaternary consumer?
    23. 23. Biomagnification http://www.ec.gc.ca/ceqg-rcqe/English/Html/Mercury/images/fig4.gif
    24. 24. Investigation 1.B <ul><li>Pg 22 all parts of the investigation </li></ul><ul><li>You should have a record of your food intake for three days. Use this information to complete the entire investigation, including the extension question. </li></ul><ul><li>This lab will be marked according to the rubric handed out in class. </li></ul>
    25. 25. Section 1.2 Review <ul><li>Pg 27 #1, 2, 7, 8, 10 </li></ul><ul><li>Connections pg 28 </li></ul>
    26. 26. Chapter 1 Review <ul><li>Make a graphic organizer that shows how energy enters the biosphere as well as how energy is transferred in the biosphere </li></ul><ul><li>Pg 30 # 1, 3, 6-9, 11, 13-15, 17 & 21 </li></ul>
