Grade Level
7th - 9th
Learning Objective
Students will evaluate how changes in abiotic factors (specifically temperature and oxygen) can cause mass changes in biotic communities by analyzing the Permian Extinction and modern ecological examples.
Timing

Total Instructional Time
Instructional Sequence
5 min
Warm-up: The Human Thermometer
Discuss as a class: "What happens to you when it gets really hot? What about when it gets really cold?"
Teacher Tip: Guide students toward physiological responses—sweating, lethargy, shivering, change in activity levels. This bridges to the concept of metabolism.
10 min
Video Viewing: The Great Dying
Watch segment 5:46 - 6:17 of "Levels of Ecological Organization."
Key takeaway: Temperature (abiotic) directly impacts metabolic rate (biotic).
Key takeaway: High metabolism + low oxygen = "suffocation" of the ocean.
25 min
Discussion & Modern Research
The Permian Puzzle Analysis:
Metabolism is the chemical reaction in the body's cells that change food into energy. Heat speeds this up. When it's too hot, organisms need more oxygen to keep up, but warm water holds less oxygen.
Modern Application Research:
Students use the Climate Impact Dossier (or internet) to research one modern example where an abiotic change (temp, water acidity, drought) is threatening a population.

Ecology Essentials
Biotic
"Bio" = Life
The living parts of an ecosystem (Plants, Animals, Bacteria).
Abiotic
"A" = Not / Without
The non-living parts that shape the habitat (Temperature, Water, Oxygen, Sunlight).
The Interaction
Abiotic factors determinewho can survive andhow they live.

The Fatal Feedback Loop
1
Temp Rises
Abiotic change: Global temperatures increase rapidly (likely volcanic CO2).
2
Metabolism Up
Biotic reaction: Animals' bodies work faster, requiring MORE energy and oxygen.
3
Oxygen Depletion
The Catch: Warmer water holds LESS oxygen. Animals "suffocate" as supply drops while demand rises.
Result: 90% of all species on Earth vanished.
Modern Echoes
The Research Challenge:
History is repeating in small pockets across the globe. Your task is to investigate a modern "Permian-style" threat.
What to look for:
What is the abiotic factor changing? (Temp, pH, Water levels?)
How is the biotic community reacting?

Marine Ecosystems: Case 01
Great Barrier Reef
Key Abiotic Factor: Temperature & Acidity
Corals are symbiotic organisms that house tiny algae (zooxanthellae). When ocean temperatures rise even 1-2°C above average, corals become stressed and expel the algae. This is "bleaching." Without the algae, the coral loses its primary food source and becomes susceptible to disease. Furthermore, as the ocean absorbs more CO2 (an abiotic gas), it becomes more acidic, making it physically harder for corals to build their skeletons.
Terrestrial Ecosystems: Case 02
The Melting Tundra
Key Abiotic Factor: Permafrost Stability
In the Arctic, the ground remains frozen year-round (permafrost). As air temperatures rise, this abiotic foundation melts. The ground becomes soft and swampy, causing "drunken forests" where trees tilt and fall because their roots cannot hold. This shift destroys the nesting grounds of migratory birds and alters the hunting paths of predators like the Arctic Fox. Additionally, melting permafrost releases trapped methane, further accelerating warming.
Arid Ecosystems: Case 03
The Sierra Nevada
Key Abiotic Factor: Precipitation Levels
Record-breaking droughts have drastically reduced water availability in the American West. Conifer trees, like the Ponderosa Pine, rely on groundwater and snowpack. When water levels drop (abiotic shift), the trees cannot produce enough resin to defend themselves against biotic threats: bark beetles. Millions of trees have died not just from thirst, but because their abiotic stress left them defenseless against predators they usually survive.
Oceanic Zones: Case 04
Ocean "Dead Zones"
Key Abiotic Factor: Dissolved Oxygen
Runoff from agricultural fertilizers enters the Gulf of Mexico, fueling massive algae blooms. When the algae die and sink, bacteria decompose them, consuming nearly all the dissolved oxygen (abiotic factor) in the water. This creates hypoxic "dead zones" where fish, shrimp, and crabs must flee or suffocate. This mirrors the Permian mechanism: an abiotic change in chemistry makes the physical space uninhabitable for high-metabolism animals.
INSTRUCTIONS: Select one case study for your ecosystem impact analysis. Identify the specific abiotic change and its cascading biotic effects.

The Permian Puzzle Recap
Based on the video, explain how these two factors interacted to cause the "Great Dying":
Abiotic Change (Temperature)
Biotic Reaction (Metabolism & Oxygen Demand)

Modern Case Study Analysis
Selected Case Study Topic: ____________________________________________________
The Abiotic Shift
Describe the non-living factor that is changing. Is it increasing? Decreasing? Changing quality?
The Biotic Impact
Which specific population is being affected? How is their survival or behavior changing?
The "Permian" Connection
How does this modern example mirror the mechanism we saw in the Permian Extinction? (e.g., supply vs demand, habitat loss, physical stress)
Section 03
Synthesis
If an ecosystem's abiotic factors are constantly fluctuating (changing wildly), what happens to the populations within that community over time?
