Which information helps scientist determine the survival probability of a population is it the feeding habits of an individual in the population the existence of natural selection in the population, the level of genetic variation in the population, or the number of offspring of an individual in the population

All of the mentioned factors can help scientists determine the survival probability of a population, as they are important components in understanding population dynamics and evolutionary processes. However, if we have to choose the most relevant information, it would be the level of genetic variation in the population. Genetic variation is crucial for a population's ability to adapt and survive in changing environments. Higher genetic variation provides more opportunities for individuals to possess advantageous traits that can help them survive and reproduce successfully.
