add And the evolution of insecticide resistance by insects, and herbicide resistance by plants. Even if the challenge were removed, if the newly developed variant were in the majority, the old variant may well still fail to prosper.

an example of an organism is people and plants
You are a good example of a multicellular organism and Escherichia coli, the microorganism living symbiotically in your intestine, is a good example of a unicellular organism.
An example on an organism is like and animal or a human.
An unicellular organism is single celled organism. For example- bacteria, archaea, amoeba
The need for a change itself. For example, the need to migrate in order to keep up with food sources would bring an organism into another territory that their bodies might not be adjusted to. Rather than dying off, the "fittest" organism of that breed might mate with another "fit" organism, and after - guessing - 20 generations or so, genetic changes will have made that territory the most suitable environment for that organism.
As an example of the selective mechanism, but artificial selection is directed by men and usually has a definite goal in mind. Natural selection is the selection of favorable variants, something like artificial selection, against the backdrop of the immediate environment. Artificial selection selects traits beneficial to the men doing the selection, while natural selections selects traits beneficial to the organism. Still, genes are changed over time in populations with both methods.

Hinduism has been changing constantly. As an example original Hinduism was the culture of Dravidians. It has changed completely throughout the course of history.
Natural selection is when the traits that make an organism survive and reproduce better in their environment become more common. An example of natural selection would be light moths changing to dark-coloredmoths to adapt to their environment. Like the tree barks they live on turning black, they too would turn dark-coloredfor better survival and an advantage to hide from predators.Artificial selection is intentional breeding for certain traits. An example would be a florist breeding two pretty plants to get a pretty plant..yeah,bad example but you get the idea lol.

No, natural selection is the mechanism that drivesevolution.
This seems to be an odd question to ask... Unless I'm mistaken, the phenotype of a given organism is governed by its genotype, and changed a fair amount by the organism's environment. Consider the following circumstances: Organism A has a long set of arms, and has a "long arm" allele. Organism B has short arms and a "short arm" allele. For example, A's genotype has the "long arm" allele, and seen in its phenotype it has long arms. The converse is true for B. Judging by your usage of technical terms in your question, I'm sure I don't need to tell you that A will out-compete B, assuming they are in a food-is-up-high environment. So, A will end up with more offspring than B, again assuming that A and B are members of different species. Eventually organism A will become prevalent, and natural selection will have caused there to be more organisms with the "long arms" phenotype, and the "long arm" allele in their genotype. In summation, Genotype governs Phenotype, and the best geno- and phenotypes will be chosen by natural selection. By an organism having a superior phenotype, it also has a superior genotype.
yes, anything living is an organism
