                                    Summary                                     

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

                               Solution Approach                                

 1 Modeled the problem with 16 state variables (4 species × 2 zones × 2         
   seasons), each assigned a population level (0, 1, or 2)                      
 2 Implemented all constraints using ASP's declarative constraint syntax:       
    • Carrying capacity limits for different species/zones                      
    • Winter scarcity restrictions                                              
    • Predator-prey balance (predator level ≤ prey level)                       
    • Biodiversity requirements (each species total ≥ 1)                        
    • Exact hawk population constraint (total = 2)                              

                            Key ASP Techniques Used                             

 • Choice rules for assigning exactly one level to each state                   
 • Integrity constraints to eliminate invalid solutions                         
 • Aggregates (#sum) for computing species totals                               
 • Predator-prey relationships modeled as facts and enforced through constraints

                                 Solution Found                                 

The solver found a valid ecosystem configuration where:                         

 • The Forest zone supports the full food chain (Grass→Rabbits→Foxes→Hawks all  
   at level 1)                                                                  
 • The Meadow has no viable ecosystem (all species at level 0 except Foxes which
   must be 0)                                                                   
 • All constraints are satisfied with perfect predator-prey balance             

The solution has been saved to 060_ecosystem_balance_hard_task_code.py and      
outputs the required JSON format.
