How do principles of natural selection help explain why there are more deaths among babies whose birth weight is low?

"Natural selection is the gradual, non-random process by which biological traits become either more or less common in a population as a function of differential reproduction of their bearers." - Wikipedia
Babies with low birth weight are more susceptible to dying because their bodies are too small to weak to sustain life. Reasons for low birth weight are varied and depend heavily on the health of the mother. It's not really a natural selection process.

How do the principles of natural selection help explain why there are more deaths among babies with low birth weights than among babies of average birth weights?
The Lord kills and makes alive. Deut 32:39 and 1 Samuel 2:6. Divine selection, not natural.
Why do living things have too many babies?
Not all babies will survive until they can reproduce. Thus, natural selection allows only the strongest to live and reproduce, eliminating the weaker babies to make more weak babies.
How did Darwin apply Malthus's ideas about human populations to the theory by natural selection?
more babies being born that people dying
Why do adults have babies yet do not lay eggs how many origins of speaces can there be?
If natural selection is correct, judging by your spelling of 'babies' and 'species' you don't have long left, just make the most of it.

What are the basics of theory of natural selection?
The biggest and best of the species breed with each other, while the weak ones die out, creating superior babies, that go on to create super, superior babies, and so on.
When organisms with certain desirable trait are mated?
Natural selection is when organisms with a desirable trait mate and produce babies with that trait. The process of elimination will eventually diminish any that do not have that trait/
Is it true or false that a natural selection acts on phenotypes not genotypes?
It doesn't. Phenotypes are viable or not in a given environment, and this influences whether the corresponding genotypes get passed on. Selection works on genotypes via the effects of their expression, their phenotype. The answer you may be looking for is that phenotypes maladapted to their environment have less babies, and pass on less copies of their genes. "Natural selection" is the whole process over generations. "Selection" may refer to misadapted bodies/phenotypes reproducing less due to illness, hunger, bad quality territories, dying earlier, etc.
