Detailed explanation-1: -Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.
Detailed explanation-2: -A species must be capable of surviving and reproducing despite changes to food sources, climate, or threats from predators. Which statement correctly describes a way that mutations increase the likelihood that a species will survive in a changing environment? Mutations are a source of variation in species.
Detailed explanation-3: -In nature, these resources are often limited, and individuals within a population must compete for resources in order to survive. Long-term survival of a species is based on obtaining resources that are limited, so that individuals can live and reproduce.
Detailed explanation-4: -Mutation is one source of variation between different groups within a species. The variation of organisms within a species increases the likelihood that at least some members of the species will survive under changed environmental conditions.
