No, natural selection is the environment!
The variant organism is selected against the immediate environment where it survives and reproduces better than it's conspecifics.
No, natural selection is believed to result in evolution.
There are three main mechanisms that can cause changes in allele frequency.These include natural selection, genetic drift, and gene flow.
Natural selection is a cause of organic evolution. It is the mechanism by which certain traits become more or less common in a population based on their advantages or disadvantages for survival and reproduction in a given environment. As organisms with favorable traits are more likely to survive and reproduce, these traits become more prevalent over generations, driving the process of evolution. Thus, natural selection leads to changes in the genetic makeup of populations over time.
Everything from available food to climate will cause the changes we see in natural selection. Random mutations occur constantly and when those mutations are beneficial for life, the genetic code is more likely to be passed on to future generations.
They help each other by gradually accumulate in a species, while unfavorable ones may disappear. Over a long time, natural selection can lead to changes.
If the species can not adapt to changes in the environment they will die out.
No, they are two different things.
No, it's exactly the other way around: natural selection causes adaptation.

Natural selection.
Natural selection and artificial selection both involve an organism's traits being determined by how much they're favored. Then, the organisms with favorable traits pass those traits on to future generations.However, natural selection is caused by survival; the organisms with traits that increase their chances for survival and reproduction pass on their traits. As for artificial selection, humans purposefully decide which traits (like the most colorful one) of an organism to pass on.The similarity of artificial selection and natural selection is that they both can cause changes in the frequency of population.
Natural selection can help creatures adapt to their enviorment. Sometimes this can cause unwanted problems.
