**Ecosystem Impact Analysis Post-Supervolcano Eruption**

**Immediate Effects (First Few Months):**
- **Plants:** Photosynthesis slows due to reduced sunlight, leading to stunted growth and possible die-off of sunlight-dependent species.
- **Rabbits:** Experience food scarcity as plant biomass diminishes, leading to increased competition and initial population decline.
- **Foxes:** Prey population (rabbits) decreases, causing foxes to face hunger, with possible minor decline or increased competition for remaining rabbits.

**Medium-Term Effects (Several Months to a Year):**
- **Plants:** Plant populations stabilize at lower levels, with some biodiversity loss as sunlight-dependent species decline. Shade-tolerant species may begin to dominate.
- **Rabbits:** Population continues to decline due to sustained food scarcity, leading to fewer rabbits available for foxes.
- **Foxes:** Population decline accelerates as rabbit numbers drop; some foxes may disperse in search of food, while others face malnutrition or starvation.

**Long-Term Effects (Years and Beyond):**
- **Plants:** Ecosystem may shift towards shade-tolerant plant species, potentially altering biodiversity and ecosystem structure.
- **Rabbits:** Population stabilizes at a lower equilibrium, reflecting reduced food resources; recovery unlikely without ecosystem change.
- **Foxes:** Population may stabilize but remain lower, dependent on rabbit numbers. Foxes may adapt by diversifying prey, though constrained by primary food source reliance.

This chain reaction underscores the cascading impact of reduced sunlight on an ecosystem, highlighting the interconnectedness of species and the potential for lasting ecological shifts.
