That individual organisms, usually of the same species, compete for food, mates, niches and all that leads to reproductive success. Thus the organism better suited to survive and reproduce successfully against the immediate environment is naturally selected to leave more progeny than organisms less suited to do this.

What principles includes variation and competition?
Natural selection.
What do variation and competition have to do with 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'.
What principals include variation and competition?
Natural selection.
What affects natural selection?
variation,overproduction, and competition
What factor of natural selection causes competition?
Overproduction
Natural selection need in order to take place?
Natural selection needs competition in order to take place.
How does competition lead to selection?
'Competition', in the context of natural selection, doesn't have to mean actual conflict, or direct competition. It refers only to the average number of fertile offspringproduced by diverse and differing variants. Some variants will manage to produce a higher average number of fertile offspring than others. In that sense, they are competing.
What role does competition play in the theory of natural selection?
Natural selection needs competition in order to occur
What is the 4 main points of natural selection?
natural selection (4 tenants) -genetic variation -overproduction of offspring -struggle for existence (competition) -differential survival and reproduction
How does overpopulation relate to natural selection?
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.
How do habitat and competition lead to speciation of Pollenpeepers on Warwick Archipelago?
how is natural selection occurring in the pollenpeepers
Why would natural selection not occur in this poplutation?
What population? Perhaps you mean if there were no variation for natural selection to select from.
