Does evolution occur just because an individual organism survives longer in an environment?

No. Evolution occurs because each generation of individuals in a population has slightly different genetics than the one that preceded it and the one that will follow it. There are many different mechanisms that bring these genetic changes about.

What is the process by which only the suited for organism environment survives?
natural selection
How does fitness relate to evolution?
Fitness to a biologist means ' reproductive fitness. ' The variant organism that survives against the immediate environment and leaves more descendants that the other organisms of his population is fit. These descendant's this organism leaves change the allele frequency of the populations gene pool and this is the definition of evolution.
Does natural selection cause changes in the environment?
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.
Are axalotles good at adapting?
If a species survives for an extended period of time then it (the species) has adapted, if it does not survive then it has not. Individuals do not adapt to their environment consciously. It is a matter of evolution and luck.
What is the term used to describe how well an organism functions in its environment?
Fitness
The range of factors under which an organism functions and survives is known as?
Bacteria
How an organism survives including its habitat and how it obtains food and shelter is called?
niche
How do species interact with their environment?
A species either survives in its environment or the environment kills it.if a species is well adapted to the environment it thrives.
How does natural variation affect evolution?
Natural selection (the driving force of evolution) is the selection of genetic variations by how they effect the organism's chances of survival or reproduction. If they diminish it's chances, the organism or it's immediate offspring die and the gene is gone. If the genetic variations increase it's chances, then it survives. Without genetic variations there can be no evolution. Natural selection is the selection (by environmental pressures) of those variations.
