(N/A) Self-consciousness is the ability of an organism to be aware of itself.
$1$. All living organisms,from the simplest prokaryotes to the most complex eukaryotes,sense their environment and respond to external stimuli like light,water,temperature,and other organisms.
$2$. However,self-consciousness,which is the awareness of one's own existence,is a unique feature of human beings.
$3$. Humans are the only organisms that are aware of themselves,have thoughts,and can reflect on their own actions.
$4$. Therefore,while consciousness (response to external stimuli) is a defining property of all living organisms,self-consciousness is restricted to humans.
