What process selects against populations that are not fit to survive in their environment?

No process.
The selection process selects variant individuals against the immediate environment. You seem to be talking about group selection which is not established biological consensus. Individuals are selected while populations evolve. Natural selection is for individuals and you need to get this concept down correctly.

Does an animal's environment affect or does it not affect its adaptation?
This is the fundamental premise of the Theory of Evolution by Natural Selection; the environment has a fundamental impact on the adaptations and evolution of organisms. The environment "selects" for those specimens that survive to have more offspring. Those animals that cannot survive are selected against.
What is being selected in natural selection?
The individual, or the genes of the individual. All organisms are variants in phenotype and behavior. So, natural selection is the immediate environment these organisms are in and those that survive and reproduce better in this environment leave more descendants which carry the genes that promoted that survival and reproduction advantage. Then those genes are more represented in the populations gene pool and this is evolution.
How does the survival of the fittest relate to the theory of evolution?
People often think of evolution as what they call survival of the fittest. However, that means a fight among members of a species. This is not what is really meant. The 'fight' is with the environment and the species and not a fight of one individual with another. If the species has a way of best surviving what the environment throws at it, it will survive. Other species might not and will die out.
Why are vestigial structures not removed by natural selection?
Nature selects against only harmful traits
How can mutations over millions of years lead to new species?
Mutations lead to all sorts of variation in organisms and natural selection selects the best able to adapt to the immediate environment by becoming reproductively successful. Thus alleles change over time in populations of organisms and evolution occurs. One; anagenesis. Where a species just evolves so much that it becomes another species. ( rare and controversial ) Cladogenesis. Where species are split asunder by physical or behavioral reasons and split into two different species.
Is natural selection a process of editing or creation?
Natural selection is the process in which the environment selects for the best traits and behaviors of a speciees. I dont think it would be either editing or creating. more of enhancing
Is natural selection a source of variation within species?
No, mutation and sexual recombination are the sources of variation and natural selection selects from those variations presented to it against the immediate environment.
Why do some environments have more types of organisms than others?
Natural selection "selects" organisms that are best suited for each environment. Those that are not fit for the environment are selected against until they migrate or become extinct all together.
Is artificial slelction part of darwin's theory?
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.

The environment "selects" for those specimens that survive to have more offspring. Those animals that cannot survive are selected against.
How does natural selection result in adaptation to the environment?
All organisms are variations and some of these variations confer survivability and reproductive success on the organism that processes the variant traits and the progeny of this organism and all against the immediate environment. Natural selection is just the immediate environment that selects these favored organisms over their conspecifics and then the progeny of these favored organisms leave greater allele frequencies of these favored traits in the populations gene pool and these trait grow to majority ststus as the adaption now seen in the population.
Why is it incorrect to say that an organism adapted to its environment?
Organisms don't adapt to their environments, rather, the environment selects for the better traits.
When a farmer selects and breeds his or hers best livestock the process involved is?
The process is called artificial selection.
Is Sodium lactate agar selective?
yes, it selects for microbes that can grow in a sodium environment and ferment lactate
What role does mutations and genetic recombinations play in evolutionary changes?
These two processes sserve up the variation in individual organisms that natural selection selects from against the immediate environment. So, the individuals selected, on the basis of greater survivability and reproductive success, over their conspecifics are the individuals that pass on these traits tp progeny and when evough of these traits become represented in the populations gene pool allele frequency shifts and evolution occurs.
How can mutation affect evolution?
Mutation can serve up the raw variation that natural selection selects from, thus alleles are changed over time in populations of organisms; evolution.
Why do scientists say that the environment selects the traits that allow an organism the survive and reproduce?
That is how organism adapts to changes in the environment in order for it to stay alive and continue its genes through its offspring.
