This process is called natural selection. It is the mechanism by which traits that provide a survival or reproductive advantage to an organism become more common in a population over time.
Wheat is a crop that has been domesticated through artificial selection, not natural selection. Humans selectively bred wild grasses over thousands of years to enhance desirable traits such as seed size, yield, and resistance to diseases, resulting in the cultivated wheat we have today.
The similarity between natural selection and selective breeding is that they both produce changes in plants and animals.
Natural selection can only work on genetic variation that already exists. So mutation comes first, then natural selection.
It hasn't. Natural selection is a key part of the ecosystem itself.

Since natural selection also means the survival of the fittest, those organisms that produce antibiotics (against life) had a weapon to keep other organisms from taking their space that they needed to grow and reproduce.

Yes. Without natural selection there might probably still be change, but it would produce a fine gradient of diverging morphologies in every 'direction' of change. Natural selection limits the 'directions' of change, thereby producing distinct morphologies and thus distinct species.
Natural selection creates a stronger species that is able to live longer and produce more. It continues to work because after a few generations, the traits will become common in the population.
