Biological Collapse Thresholds: Admissibility Limits in Biological System Stability

Biological systems maintain stability through coordinated interactions between cellular regulation, energy metabolism, environmental conditions, and structural organisation. These interactions must remain within biological constraint boundaries that permit organism persistence. This paper interprets biological collapse through the Paton System framework as a failure of admissibility conditions governing biological system stability. Biological systems remain viable only when physiological processes operate within structural, energetic, and regulatory limits. When these limits are exceeded, instability may emerge in the form of metabolic failure, systemic breakdown, or organism collapse. Biological collapse thresholds therefore represent the boundary conditions separating stable biological organisation from system failure. Interpreting these thresholds through admissibility clarifies how biological systems maintain persistence while remaining compatible with underlying biological constraints.
