O que são organismos vivos? 

Uma definição inusitada aparece neste livro:

Living organisms are highly organized chemical systems that comply with the first and second laws of thermodynamics. They are low-entropy systems which (1) must obtain energy from external sources and (2) to support life, must have a continuous energy flow. Upon death, the flow of energy stops and entropy tends to a maximum.

Nada como ver o mundo segundo diferentes perspectivas...
