1. Ecology

3. Terms to Know
Consumer = heterotroph = organisms that must get their energy from other organisms
Producer = autotroph = organisms that can make their own food

4. Arrows show the flow of ENERGY
Killer whale
Tertiary consumer
Arrows show the flow of ENERGY
Leopard seal
Tertiary consumer
Cod fish
Secondary consumer
Krill shrimp
Primary consumer
algae
producer

6. Terms to Know
Phytoplankton = small, often microscopic autotrophs that float/drift around in the ocean
Phyto means light
Plankton means drifter
Zooplankton = small, often microscopic heterotrophs that float/drift around in the ocean
Zoo means animal (heterotroph)
Consumer = heterotroph = organisms that must get their energy from other organisms
Producer = autotroph = organisms that can make their own food

7. Do this in logbook on left side.
Write down one food chain from this food web and label the levels of producers and consumers.
What is the difference between a food web and a food chain?

8. Do this in logbook on left side.
What is missing from this food web?

9. Organisms that break down dead organisms
Decomposers
Organisms that break down dead organisms
Bacteria
Worms
Insect larva
Fungi
Protists
Insects

13. Watch the video about the Energy Pyramid

14. In your own words explain what is shown in the energy pyramid to the left.

15.
Draw a two column chart in your log book on the left side of the obs/infer notes page like so:
Watch this video clip
While you watch write down observations and inferences
After the clip write at least two testable questions for the video clip and describe how you would test the questions.
Observations
Inferences

16. Practice
Using Food Web WS follow directions and do in logbook left side.
Using Pyramid Directions make pyramid

17. Relationships Symbiotic Relationship
A close, long term relationship between organisms of two different species where at least one organism benefits
Called Symbiosis
Three kinds, Parasitism, Mutualism and Commensalism

18. Parasitism
Symbiotic relationship where one organism benefits and the other is harmed

19. Mutualism A symbiotic relationship in which both organisms benefit

20. Commensalism
A symbiotic relationship in which one organism benefits and the other is unaffected

21. REDO Work Part 1 Do this OYOP
Write down two different food chains from this food web and label the levels of producers and consumers.
Now go to the next slide and do another two food chains.

22. REDO Work Part 2
Write down two different food chains from this food web and label the levels of producers and consumers.
