One systemic definition of life is that living things are self-organizing and autopoietic (self-producing). Variations of this include Stuart Kauffman's definition as an autonomous agent or a multi-agent system capable of reproducing itself, and of completing at least one thermodynamic work cycle. [27]
A person's life has meaning (for themselves, others) as the life events resulting from their achievements, legacy, family, etc., but, to say that life, itself, has meaning, is a misuse of language, since any note of significance, or of consequence, is relevant only in life (to the living), so rendering the statement erroneous.
Living systems are life forms (or, more colloquially known as living things) treated as a system. They are said to be open self-organizing and said to interact with their environment. These systems are maintained by flows of information , energy and matter .
Meaning can be defined as the connection linking two presumably independent entities together; [2] a meaningful life links the biological reality of life to a symbolic interpretation or meaning.

The classification of living things into animals and plants is an ancient one. Aristotle (384–322 BC) classified animal species in his History of Animals, while his pupil Theophrastus (c. 371 –c. 287 BC) wrote a parallel work, the Historia Plantarum, on plants. [7]
The community of living organisms in conjunction with the nonliving components (e.g., water, light, radiation, temperature, humidity, atmosphere, acidity, and soil) of their environment is called an ecosystem. [147] [148] [149] These biotic and abiotic components are linked together through nutrient cycles and energy flows. [150]
The term "organism" (from the Ancient Greek ὀργανισμός, derived from órganon, meaning ' instrument, implement, tool ', ' organ of sense ', or ' apprehension ') [2] [3] first appeared in the English language in the 1660s with the now-obsolete meaning of an organic structure or organization.
