Consider a major environmental change. if there are not organisms in a population that have traits that allow them to still continue to survive to reproduce, what would likely happen to that population

If there are no organisms in a population that have traits that allow them to continue surviving to reproduce, it is most likely that this species will become extinct.

Explanation:

A species becomes extinct when the last member of that species dies, this becomes a certainty, since there will be no animals or plants that belong to that species that are able to reproduce to create a next generation. A species can be considered extinct even when there are individuals alive but unable to reproduce, as a result of the dispersion of the species, the advanced age or lack of individuals of the opposite sex, etc.
