Natural selection occurs when a certain environment favors a particular characteristic or trait over another. With this being said, when a species becomes extinct, this means that that species' particular set of characteristics or traits was not the most favorable for them to survive in that certain environment.

Explain how natural selection is at work when a species becomes extinct?
According to science, natural selection chooses the best features for the best survival. When those processes do not occur for some reason, the species does not survive.
How natural selection help few species to survive and how few others got extinct?
how natural selection help some species to survive and few got extinct
Why do most species in the world go extinct?
Notincluding human intervention. Natural selection.
Natural selection allows a species to change in response to its environment. What is the process by which a species becomes better suited to its environment called?
Adaptation (I'm studying the same thing ;)
What influence did speciation have on Darwin's development of Natural Selection?
The influence of providing an explanatory mechanism for what was obvious to Darwin; species arose and species went extinct.
When no living member in your species exist the species?
when there are no living members of a species the species is said to be "extinct".
According to the theory of natural selection a species that lacks the variations necessary to adapt to a changing environment will most likely do what?
Go extinct.
When a species permanently disappears the species is said to be what?
It becomes extinct.
What is the process by which a species becomes better suited to its environment called?
Sometimes this is called natural selection.
What are the two major reasons why a species becomes extinct?
1) a natural catastrophe (eg an asteroid impact) 2) evolutionary changes.
When plants and animals cease to exist they are said to be?

Why does the presence of extinct and transitional forms in the record support the pattern component of the theory of evolution by natural selection?
supports hypothesis that species have changed over time.
