(N/A) Living organisms are open systems that maintain a state of low entropy (high order) by constantly exchanging energy and matter with their environment.
According to the $2^{nd}$ law of thermodynamics,the entropy of an isolated system always increases over time.
In living organisms,metabolic processes require energy to maintain cellular structure and repair damage.
As an organism ages,its ability to efficiently utilize energy to counteract the natural increase in entropy declines.
Eventually,the accumulation of disorder (entropy) within the biological system exceeds the organism's capacity to maintain homeostasis,leading to the breakdown of vital functions and ultimately death.
