Of the five characteristics of living things which one is required for the species to survive but does not have to apply to an individual
The characteristic that is required for the species to survive but does not necessarily have to apply to an individual is "reproduction." While individuals within a species do not have to personally reproduce for the species to survive, the species as a whole must reproduce in order to continue its existence.
The characteristic of living things that is required for the species to survive but does not have to apply to an individual is reproductive ability.
While not every individual in a species may reproduce, the species as a whole must have the capability to reproduce in order to continue its existence over time. Reproduction allows for the passing on of genetic material and ensures the survival of the species. Individual organisms may not have reproductive ability due to factors such as age, illness, or physical limitations, but as long as some members of the species are able to reproduce, the species can continue to survive.
