Trophic coherence explains why networks have few feedback loops and high stability

(Phys.org)--Complexity - defined as having emergent properties or traits that are not a function of, and are therefore difficult or inherently impossible to predict from, the discrete components comprising the system - is a characteristic of complex systems at a wide range of scales (such as genes, neurons and other cells, brains, computers, language, and both natural and sociopolitical ecosystems) that comprise interconnected elements capable of self-modification via feedback loops.
