L.T.: I can explain how yesterday’s demo is a
model of cellular respiration and I can
prepare for the test tomorrow.
DO NOW: How does the demo from
yesterday model cellular respiration?
…………………………..
Reflection: What topics on the test am I still
unsure of? What do I need to do tonight to
fully prepare for this test?

• As you watch the video clips, please add notes about:
• - How each function works
• - Who uses these functions
• - How they connect with energy flow in ecosystems
PS/RS
• Ecosystem Parts: (LS2A)
• - individual, populations, communities, ecosystems, abiotic
factors

Energy Flow in an Ecosystem:
- food webs: feeding relationships (LS2B)
- trophic levels: producers, consumers, decomposers (LS2B)
- 10% rule: biomass pyramid (LS2B)
- PS/RS: how energy enters and leaves an ecosystem (LS2C)

Organisms
What ecosystem
descriptions
could we apply
to these frogs?
• Make a 6 part food chain from Mono
Lake.
Organize this food web
into trophic levels
• How do abiotic factors affect organisms?
1. What trophic
level does the
snake belong to?
Why?
2. Let’s say the
grasshopper and
the frog both
need 10 food
items daily to
survive. How
many blades of
grass are needed
to support 1 frog?
Why?.
• Explain the crucial role that producers
play in an ecosystem.
• How do plants make their own energy?
• Organize the following words into categories:
1. Herbivore 2. Primary consumer 3. producer 4. decomposer
5. detritivore 6. carnivore 7. omnivore 8. secondary consumer
9. top predator 10. photosynthesis 11. respiration 12. heterotroph 13.
autotroph 14. consumer
This is an individual CA gull.
Can it also be a population?
Why or why not?
• Explain the relationship between
photosynthesis and respiration.
• What is the difference between
decomposers and detritivores?
• What trophic level do decomposers
belong to?
• Explain how both 1 square foot of
Stewart’s lawn and the Puget Sound can
both be considered an ecosystem.
