                                    Summary                                     

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

                               Solution Overview                                

The ASP model finds a stable population distribution for 4 species (Grass,      
Rabbits, Foxes, Hawks) across 2 zones (Forest, Meadow) and 2 seasons (Summer,   
Winter), with each of the 16 states assigned a discrete population level (0, 1, 
or 2).                                                                          

                          Key Features of the Solution                          

 1 Efficient Modeling: Used choice rules to generate exactly one population     
   level for each species-zone-season combination                               
 2 Comprehensive Constraints: Implemented all 5 constraint groups:              
    • Carrying capacity limits                                                  
    • Winter scarcity restrictions                                              
    • Predator-prey balance (predator ≤ prey in same location)                  
    • Biodiversity requirements (all species total ≥ 1)                         
    • Exact hawk population (total = 2)                                         
 3 Valid Solution Found: The solver found a balanced ecosystem where:           
    • Forest supports the full food chain (Grass→Rabbits→Foxes→Hawks, all at    
      level 1)                                                                  
    • Meadow has abundant grass (level 2 in summer, 1 in winter) but no         
      predators                                                                 
    • All constraints are satisfied                                             

                                     Output                                     

The solution is formatted as JSON with population levels for all 16 states,     
predator-prey relationships, and a balance_achieved flag. The code has been     
saved to 060_ecosystem_balance_hard_task_code.py.
