Biological systems ranges from Ecosystems to the system of reactions that form cellular biochemistry. Usually, we refer to the latter: systems of biochemical reactions that make cells work It is often said that biological systems such as cells, are complex systems 2005-3-24 Chaoqun Wu, Fudan University
