                                    Summary                                     

I've successfully completed the ecosystem modeling task using Answer Set        
Programming (ASP) with the clingo Python API. Here's what was accomplished:     

                               Solution Overview                                

Stable Populations Found:                                                       

 • Grass: 96 units                                                              
 • Rabbits: 4 units                                                             
 • Foxes: 1 unit                                                                
 • Hawks: 1 unit                                                                

Food Web Relationships:                                                         

 • Rabbits → Grass (consumption rate: 0.4)                                      
 • Foxes → Rabbits (consumption rate: 0.1)                                      
 • Hawks → Rabbits (consumption rate: 0.5)                                      
 • Hawks → Foxes (consumption rate: 0.5)                                        

                           Key Implementation Details                           

 1 ASP Model Design: Used choice rules to select population levels (1 to        
   capacity) and consumption rates (0.1 to 0.5) for each species and feeding    
   relationship.                                                                
 2 Constraints Implemented:                                                     
    • Herbivore sustainability: Rabbits ≤ 0.5 × Grass ✓                         
    • Predator sustainability: Foxes ≤ 0.3 × Rabbits ✓                          
    • Hawks sustainability: Hawks ≤ 0.3 × (Rabbits + Foxes) ✓                   
    • No extinction (all populations > 0) ✓                                     
    • Populations within carrying capacity ✓                                    
 3 Optimization: Maximized total biodiversity (sum of all populations) to find  
   the healthiest ecosystem state.                                              
 4 Ecosystem Health Metrics:                                                    
    • Biodiversity index: 0.198 (Shannon diversity)                             
    • Stability score: 0.348 (capacity utilization)                             
    • Sustainability: True                                                      
    • Balance achieved: True                                                    

All constraints are satisfied and the solution represents a stable, sustainable 
ecosystem configuration.
