1.Energy flows through (lost as heat); matter cycles
2.Pyramids can be disrupted by invasives, disease, or climate
REFSTUDY GUIDE: Big Ideas (W1-W5 Synthesis)Use to answer form questions
1.Energy flows one direction while matter cycles.
Sun -> Producers -> Consumers -> Heat (lost forever). Matter: Living
-> Dead -> Decomposed -> Living (recycled).
2.The 10% rule creates pyramidal structure. Energy
scarcity at each level drives natural selection and limits predator
populations.
4.Ecosystem services are the foundation of human survival.
Protecting biodiversity = protecting trillions of dollars in
services we depend on.

WRITESYNTHESIS PHENOMENONYour initial thinking
How do energy flow, matter cycling, food web complexity, and
ecosystem services create sustainable ecosystems?
This week brings together ALL concepts from C4: the 10% rule (W1),
invasive species (W2), decomposition (W3), biodiversity (W4), and
ecosystem services (W5). How do these pieces fit together?
Your initial thinking - how do all these concepts connect?
I think these concepts connect because...

Q1 (CUMULATIVE):How do W1-W5 concepts connect to create sustainable
ecosystems?
Q2 (SYNTHESIS):Why is biodiversity essential for BOTH ecosystem stability AND
ecosystem services?
Q3 (INTEGRATION):Explain why "energy is recycled in ecosystems" is WRONG. Use
specific evidence.
