Sar: (Discussion) flesh out more

[MKLau]

Based on AME's re-arrangement, the current structure of the discussion is:

• Current model improves the Sirota 2013 model
• Model replicates the behaviors of other models
• Complex systems theory suggests systems boundaries are arbitrary and that scales are possibly heuristically disconnected
• Comparison with other food webs suggests that the model is spatially and temporally scalable
• Pitcher ecosystem is a useful tool
