G.O.T. = Get On Task Ecology MY GOAL Measurement TOPIC 6,7,8 MY GOAL G.O.T. = Get On Task Mon 10.08.12 Ecology I will… pass the 1st MiniSummative today on Ecology! Review a few minutes before MiniSummative!

Levels of Organization….

Food Chains vs Food Webs They both start with PRODUCERS They both show transfer of ENERGY. Food chain less levels  Food web shows all feeding relationships http://www.copernicusproject.ucr.edu/ssi/HSBiologyResources.htm

Which FOOD CHAIN is written correctly?

  ISN page 49  Review ! 10 % Rule!! If a new predator is introduced in to a food web, other populations would ( or ), thus ( ing or ing) the amount of ENERGY available for other things.

Review of Food Web Page 410 in textbook Tertiary consumer? Autotrophs? Heterotrophs? Decomposers????? Reef Shark Algae, Phytoplankton Shark, Turtle, Jellyfish, Parrotfish Sponge, Shrimp, also Zooplankton None shown

Trends in Trophic Level Diagrams What do you notice about the numbers of organisms from bottom to top? How does the size of the organism change as you move through the levels? What # level in the energy pyramid is held by the producers? Where is there more ‘biomass’ & more energy in a trophic pyramid? What organism in the pyramid above has the greatest energy needs? So WHY are there fewer consumers at the top? 5 4 3 2 1 Get fewer gets larger Level 1 Bottom – level 1 hawk Less energy avail – hawk has more energy needs

Explain Autotroph Heterotroph Decomposer Food Chain Food Web Primary Consumer 2nddary Consumer Tertiary Consumer B A E C D H G F Consumer; must go get its food Producer; must MAKE its own food through photosynthesis or chemosynthesis Shows transfer of energy in a short series of feeding relationships Shows complex feeding relationships Breaks down dead & decaying organisms thus sending nutrients to the soil Carnivore that eats secondary consumers Carnivore that eats primary consumers Eats plants = herbivore

MiniSummative MT 6,7,8 Ecology Everything under white board, that means: (Book bags, All technology) Pick up CPS Remote & assessment paper Take MiniSummative  READTHINK UNDERSTANDANSWERDOUBLECHECK Power Down remote – Turn in with quiz paper Complete assignment on next slide………………

YOUR JOB After MiniSum RIGHT SIDE ISN p.55 Cycles LEFT SIDE ISN p.54:

Answer on ISN page 54 4 elements make up 96% of body? 2. Another word for Water Cycle? 3. Water comes from? (3 sources) 4. Oxygen is a waste product from? 5. Plants get CO2 from? 6. Building block of life? 7. ? ‘fixes’ N so we can use it C, H, O, N Hydrologic Precip, Evap, Transpiration Plants NITROGEN CARBON OXYGEN WATER Exhalation Carbon Bacteria
