As nature changes (think of weather, season, natural disaster and the way species eat each other) certain element of nature will go extinct causing the species that fail to reduce their dependency on that extinct element perish as well.
Put it on a modern perspective...
How bright and or a hard working students will get all the priviledges and leave the underachiever to find their own way also a kind of "natural selection". Students that fail to change their behaviour to work harder or smarter will have a more challenging life.
Natural selection is the mechanism primarily responsible for the development of today's biodiversity.
Natural selection
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.
No, a frog is not an example of natural selection itself. Natural selection is a mechanism for evolution that acts on populations of organisms over generations, influencing the traits that are passed on to the next generation. Individual organisms like a frog can be impacted by natural selection, depending on their traits and how those traits affect their survival and reproduction.
Natural selection produces adaptations in organisms that increase their fitness and survival in a given environment. Through the mechanism of natural selection, organisms with advantageous traits are more likely to survive and reproduce, leading to the gradual evolution of populations over time.

Natural selection.
Natural selection is only the result of changing environments, mutation and the variation resulting therein. Natural selection is the process of adaptive change and the main mechanism of evolution that leads to speciation. Natural selection is a process as mutation and variation are grist to the mill of natural selection.
Natural selection- which is the mechanism driving evolution
The leading theory concerning the mechanism of evolution is natural selection.
Both Charles Darwin and Alfred Russel Wallace independently discovered natural selection.
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.
