A large population of red ants living in a forest would most likely have the greatest survival success during a long period of environmental changes. This is because a large population provides genetic diversity, which increases the chances of some individuals having traits that are advantageous in the changing environment. Additionally, ants are known for their ability to adapt quickly to different conditions and their efficient social structure, which allows them to work together for the survival of the colony. The forest habitat also provides a diverse range of resources for the ants to thrive on.Rate this question:
