Differential reproductive success is the effect that produces natural selection. Natural selection is the result of some variants within a population having more reproductive success, producing (on average) more offspring, than other variants, thereby increasing their stake in the population gene pool.
An early catchphrase coined to indicate this process is survival of the fittest. This catchphrase is wrong - or at least misleading. It suggests to the layman that natural selection is about the less-fit dying, while the fitter survive. But as explained above, it is not as simple as that: it is about the less-fit fading from the population, whether through death or because they are out-reproduced by the fitter variants. In this context 'fitness' does not mean stronger, or faster, or smarter or even healthier: it means having a larger average number of offspring.
The best adapted organisms are likely to have many offspring that will survive.

Everything! Survival is the race, but reproductive success is the finish line. Remember; individuals die, populations evolve.
The assurance of reproductive success.
Overproduction of offspring and more changes like adaptation for survival.
Natural selection is the nonrandom survival and reproductive success of randomly varying organisms selected against the immediate environment. Like that. Remember this little explanation and you have natural selection down pat

To enhance their survival and reproductive success
A simplified explanation. Natural selection is the nonrandom survival and reproductive success of randomly varying organisms who by this reproductive success change the allele frequency over time in populations of organisms, which is evolution.
Anything that leads to survival and reproductive success is, generally, an intrinsic adaption. If a butterfly were to mimic another butterfly that was poison to it's predators then those self same predators would tend to leave the non-poison butterfly alone as well as the poison butterfly thus leading to survival and reproductive success for the mimic.

Survival of the fittest
Differences between individuals may affect differences in their average reproductive success, causing the variant traits of individuals that have greater reproductive success (fitness) to become more prevalent in a given environment than rival traits. As environments change, so may the traits that have a reproductive advantage change. This is natural selection.
The "struggle to survive", "survival of the fittest" and "natural selection" are all phrases to indicate the main guiding mechanism of evolution: differential reproductive success.
Theory of evolution by natural selection. Natural selection is the nonrandom survival and reproductive success of randomly varying organisms. That simple.
It is necessary for species survival as a whole. Although reproduction generates an individual, the individual's own reproductive system is not necessary for its survival; although loss or damage to the organs may have deleterious effects beyond loss of breeding ability.
to ensure the survival of a species.
To encourage and ensure copulation and survival of the species.
