Which characteristic of living things is important to the survival of a group of animals rather than an individual member of thi
sammy [17]

Answer:

If a whole specie of organisms has to survive, they should must possess the ability to reproduce and adopt to environmental conditions in better way.

For example: If a disaster occurs or a condition of unfavorable weather occurs, the specie will survive even if only few members remain alive. Because those members will reproduce and regrow the community.

The reason is this that reproduction is not important for the survival of one organism, like organism will still survive even if he do not reproduce, but if a whole specie has to survive and continue, reproduction is most important trait.
