I will… pass the 1st MiniSummative today on Ecology!
Review a few minutes before MiniSummative!

2. Levels of Organization….

3. 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

4. Which FOOD CHAIN is written correctly?

5. 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.

6. 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

7. 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

8. 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

9. 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
