Question
2. SEP Use Models Think about how the event or system represented by your model might change over time. Use your model to make a prediction about the behavior of the investigative phenomenon. Your prediction should identify both the factor(s) causing the change and the anticipated effect(s).

To create a predictive model based on the scientific event or system, we can follow a structured approach. Let’s assume we are examining the impact of climate change on a specific ecosystem, such as a coral reef system.
### Model Overview
**Event/System:** Coral reef ecosystems
**Key Factors:** Water temperature, ocean acidification, pollution, and overfishing
### Prediction
**Anticipated Changes Over Time:**
As factors such as global temperatures rise due to climate change, the following changes are anticipated in coral reef ecosystems over the next several decades:
1. **Increase in Water Temperature:**
- **Causing Factor:** Global warming leading to higher ocean temperatures.
- **Anticipated Effect:** Increased thermal stress on coral, resulting in coral bleaching. Bleached corals lose their symbiotic algae (zooxanthellae), which are vitally important for their nutrition and energy production. This could lead to widespread coral mortality, substantially reducing the biodiversity of the reef ecosystem.
2. **Ocean Acidification:**
- **Causing Factor:** Increased CO2 levels in the atmosphere lead to higher levels of carbonic acid in the oceans.
- **Anticipated Effect:** Reduced calcification rates in corals, resulting in weaker and more fragile coral structures. This effect not only compromises the integrity of reef habitats but also affects the marine species that rely on reefs for shelter and food.
3. **Pollution (Nutrient Runoff and Plastics):**
- **Causing Factor:** Increased urbanization and agricultural activity leading to nutrient runoff into the oceans.
- **Anticipated Effect:** Eutrophication can promote harmful algal blooms that further stress corals. Additionally, plastic pollution can physically damage corals and lead to entanglement for marine creatures, further degrading the ecosystem.
4. **Overfishing:**
- **Causing Factor:** Unsustainable fishing practices targeting key species.
- **Anticipated Effect:** The removal of certain species disrupts the ecological balance of the reef. For instance, the decline of herbivorous fish can allow algae to dominate, choking out coral populations and diminishing habitat complexity.
### Conclusion
In summary, the combined effects of rising water temperatures, increased ocean acidification, pollution, and overfishing are predicted to lead to significant declines in coral reef health and biodiversity over time. These changes not only impact the coral and associated species but also the human communities relying on reefs for fisheries, tourism, and coastal protection. Therefore, proactive management and mitigation efforts are crucial to safeguard these vital ecosystems for future generations.
