Curve Analysis
Where is the growth exponential? Where does it level off?
What evidence shows the carrying capacity?
Limiting Factors
What biotic or abiotic factors could make the wildebeest population overshoot carrying capacity and then drop below it?
Predator–Prey Interdependence
Compare the lion graph to the wildebeest graph.
How do changes in the wildebeest population affect lions?
Predict what would happen if the apex predator (lions) were removed.
Direct Impact:
How might this development affect the wildebeest and lion populations in the short and long term?
Interactions & Feedbacks:
How could changes in these two key populations ripple through predator–prey relationships and the overall food web?
Costa’s Level 3 – Predictive Thinking:
Based on what you know about energy flow and ecosystem dynamics, predict how other components of the ecosystem—such as plant communities, scavengers, smaller herbivores, and soil nutrient cycles—might change if the resort is built. What evidence or reasoning supports your prediction?
