Presentation Transcript

  1. Wednesday 1-15-14 Turn in any late work • Warm up • Check Finches Lab & Natural Selection Internet Activities • Biomagnification • Ecology Review Journal Check! Next week

  2. Warm UP Copy data table & Complete using food web Producer Increase (Fewer Predators) Herbivore Increase (less competition) Omnivore Decrease (less prey to eat)

  3. Check Finches Lab & Natural Selection Internet Activity

  4. Page 96 (Ecology Notes) Add: • Competition: Organisms that fight over limited resources (food, mates, habitat) • Photosynthesis: Water + carbon dioxide  Glucose + Oxygen Sun

  5. Biomagnification

  6. Biomagnification(Write this on paper!) • Concentration of pesticides increases along the food chain • Because each trophic level eats multiple “infected” organisms so it all adds up

  7. “Organic” food = No Additives Non-Organic • Fruits and Vegetables treated with pesticides (if you eat a lot of these then the pesticides build up) • Hormones given to dairy cows to produce more milk is passed along to the consumer (rBGH-treated cows have increased levels of a hormone that increases growth (IGF-1 Insulin growth factor)

  8. To Do: • Staple Biomagnification to review • Review (1/2 should be completed before tomorrow, The whole thing is due Friday) • Study for tomorrows quiz
