In a sense, one might say that this is the case. But in a more direct sense, natural selection determines which organisms do not get to procreate (as much). Natural selection is therefore more a limiting phenomenon than an enabling one.
Natural selection determines the survival of groups of organisms because the ones that are doing the best are the ones that live to reproduce. These tend to pass their characteristics on to their young, creating a group of similar organisms that have the traits needed for survival.
As is consensus now, natural selection determines the differential survival of INDIVIDUAL organisms. Although very few modern biologists still regard group selection as a viable model, it is an ongoing debate in evolutionary Biology and is no where close to consensus acceptance.
An individual that is best adapted to the environment, which is how selection works, leaves the most decedents who also have these survival traits. Remember, differential survival is reproductive success in the immediate environment. This is true fitness; reproductive fitness.
natural selection is the survival of the fittest. for example: the cheetah will automatically scan a heard of antelopes for the weakest individuals, for they will be easier to pray on. therefore only the fastest and strongest will be allowed to live on and reproduce... carrying out their gens.
there are minute physiological differences between individuals of the same specie that create a better quality of life and nature "selects" those individuals for reproduction. therefore natural selection determines evolution.
Organisms are affected by Natural Selection because Inherited characteristics affected the likelihood of an organism's survival and reproduction.
Evolution is the change in allele frequency over time in a population of organisms. Change over time and a fact. Natural selection is the nonrandom survival and reproductive success of randomly varying organisms and explains much about the fact of evolution.
Artificial selection is anthropogenic -- humans interfere with nature to determine what traits get passed on, whereas natural selection is when through sexual reproduction the traits passed on are determined by survival of the fittest.
Natural Selection
he developed the idea of natural selection
They evolve and adapt so they have traits hat are useful to them, by Natural selection. This means that members of a species that are isolated, well, natural selection makes those with the best chances for survival mate with each other and produce offspring with that trait.
Because all organisms vary and different one have different survival characteristics that are selected for. Some organisms are reproductively successful and are selected to survive and pass on this success to their progeny.

Natural Selection.
Survival of the fittest is a not quite accurate phrase for natural selection. Natural selection is, The non-random survival and reproductive success of randomly varying organisms.
Natural selection
Organisms are affected by Natural Selection because Inherited characteristics affected the likelihood of an organism's survival and reproduction.

Natural selection is the non-random survival of randomly varying replicating organisms.
natural selection (4 tenants) -genetic variation -overproduction of offspring -struggle for existence (competition) -differential survival and reproduction
Malthus's idea was that our food production grows at a linear rate, while our population grows logistally. More people are being born than can be fed. Thus this leads competition for survival. Darwin observed that this is true for all organisms. More offsprings are born than can be sustained, thus leading to differential survival of organisms, thus natural selection.
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.
