Of the five characteristics of living things, Which one is required for the species to survive but does not have to an individual

The characteristic of reproduction is required for a species to survive but does not have to be present in an individual. Reproduction ensures the continuation of a species by producing offspring that inherit its genetic material and traits. While not every individual within a species needs to reproduce, the ability of the species as a whole to reproduce is crucial for its long-term survival.

The characteristic of adaptation is required for a species to survive but does not have to be present in every individual. Species must adapt and evolve over time in response to changes in their environment in order to survive. While not every individual within a species may possess the necessary adaptations, those that do will have a higher likelihood of survival and passing on their traits to future generations.
