'competition between mates' as the words suggest mean that organisms in a habitat compete for their basic needs including mates. three tigers could be competing for one tigress. and the one that's the fittest wins (survival of the fittest).
when thinking about 'natural selection', think evolution. this is to say, over time, the traits that are strongest in an organism gets passed on from one generation to another. what you get as an end result is you may notice the weaker traits have extinguished while the stronger traits have become more obvious.
now the correlation between the two: imagine having two tigers fighting for a tigress. the stronger one with sharper claws and teeth wins the tigress over. this simply means the weaker tiger probably had some flaws in its traits. and because this winning tiger has strong traits, they get passed on and that's evolution (natural selection).
Variation and competition are the basis of natural selection.When a population of organisms has variety (big/small, fast/slower, etc), and there is competition, then some of those traits will assist in winning the competition, and some will not, which will tend to mean the difference between an organism surviving versus not surviving, which in a large population will mean passing the genes for those advantageous traits on, which then means that those traits have been 'selected' for by the natural act of competition, thus 'natural selection'.
Natural selection needs competition in order to occur
natural selection (4 tenants) -genetic variation -overproduction of offspring -struggle for existence (competition) -differential survival and reproduction
There must be genetic variation, the variation must be heritable, and there must be differential reproduction (due to competition).
A hypothesis is an educated quess while a theory is a widly supported idea. The relationship between them is that they both aren't necessarily correct. An example of a theory is the theory of evolution and natural selection. They have a lot of facts to back them up, but there is no inconclusive evidence to prove they are laws of science.
Here is a quote: "The relationship between adaptation and natural selection does not go both ways. Whereas greater relative adaptation leads to natural selection, natural selection does not necessarily lead to greater adaptation." I do not recall who said it, but this is what the relationship between both is. Here is a quote: "The relationship between adaptation and natural selection does not go both ways.

Natural selection.
When competition occurs between species, the stronger species remain. This process is called: natural selection.
Overproduction
Natural selection.
Variation and competition are the basis of natural selection.When a population of organisms has variety (big/small, fast/slower, etc), and there is competition, then some of those traits will assist in winning the competition, and some will not, which will tend to mean the difference between an organism surviving versus not surviving, which in a large population will mean passing the genes for those advantageous traits on, which then means that those traits have been 'selected' for by the natural act of competition, thus 'natural selection'.
Natural selection needs competition in order to occur
Natural selection ' selects ' from among variations. Some organisms are better suited to their immediate environment and survive and out reproduce other organisms. All these organisms are genetically variant. That is the simple connection between natural selection and genetic variation. ( that variation coming about by mutation and recombination )
natural selection (4 tenants) -genetic variation -overproduction of offspring -struggle for existence (competition) -differential survival and reproduction
Natural selection is the nonrandom process by which biological traits become either more or less common in a population as a function of differemtial reproduction of their bearers. One of the main processes by which natural selection takes place is the competition over resources. The larger the population in a certain area, the more competition takes place. In the long run, it doesn't matter wheather or not the area is overpopulated; within any and every population, competition over resources takes places, so, in turn, natural selection does, too.
