Welcome to the Ecosystem Building module. Your goal is to create a sustainable food chain of exactly 8 species.
🎯 The Objective
- Every species must have enough food (Calories Provided > Calories Needed).
- The chain is typically 8 species long.
- The ecosystem must be balanced across dimensions like Depth and Temperature.
🛠️ The Solver Tool
This tool combines a Data Grid, Visual Matrix, and Automated Solver.
Data Grid
Enter species data. Use
Tab / Ctrl+D.Distribution Matrix
Visualize distribution in real-time.
Combinatorial Solver
Instant error highlighting via tooltips.
About the Author
The Ecosystem Module of the McKinsey Solve / Problem Solving Game (PSG) is not a biology test — it’s a consulting capability assessment.
It evaluates:
- Analytical structure
- Systems thinking
- Prioritization under uncertainty
📊 Ruleset
🦠
Start with Producers
Ensure a solid base (high calories, 0 needs).
📉
Mind the Gaps
Use the Matrix to spot empty ecological niches.
🤖
Use the Solver
Let the algorithm find 5+ sustainable chains.
Key Insights
- 1Producers: Base of chain.
- 2Consumers: Eat 1 prey or 2 (50/50).
- 3Flow: Calories dictate survival.
