In being all about bonding, chemistry is a study in entanglement. The ambient world of matter is molecular. Molecules are ongoing collaborations among chemical species.
Life is an entangled diversity at every level. Populated by legions of proteins working together, even the simplest cell is brimming with intertwined complexity. Multicellularity exponentially entwines synchrony with variety to achieve macroscopic life.
All life is dependent upon the habitat in which it lives: an entanglement of the organic with the inorganic. Beyond biomes and ecosystems, the Earth itself is enmeshed with all that lives in or upon it, as encompassed in the term ecology. The sporadic mass extinction events that severely shuffle life on Earth melodramatically illustrate the point.
English environmentalist James Lovelock coined Gaia to characterize the entanglement of Earth: the inextricable entwining of geophysical dynamics with biotic interactions at the planetary level. The systemic gyre of Gaia was scorned by reductionist scientists, who religiously refused to countenance ecology on a global scope. But ample evidence supports Lovelock’s gyral theory. Microbes were shaping the atmosphere eons before manmade climate change.
Planets depend upon their suns, the light and warmth of which are processes of physics and chemistry that produce matter and recycle it, thus providing for the next generation of stellar formation. The swing of star systems is an interstellar ballet, as is galactic kinesis, and so on up to the largest cosmic structures.
Consider phenomena at every scale as processes, not objects, and you may readily perceive that existence is defined by entangled interactions, not the more apparent diversity of bodies.
