What are the characteristics necessary to be considered alive?

Answer 1

Something is alive if it can reproduce, respond to changes in his/her/its surroundings, can convert some form of energy into energy to sustain his/her/its self, and has DNA. Thus, a virus is not alive because it can not reproduce on its own-it needs a host. A baby human is alive for the above four reasons (though reproduction is a capacity that will develop with maturity).

Answer 2

To be considered alive, an organism must display certain characteristics such as growth, reproduction, response to stimuli, metabolism, cellular structure, and the ability to adapt to the environment. These characteristics collectively define life.
