Variation within the species would mean that individuals are likely to react differently to environmental change. This means that they may not all have a negative reaction, and therefore the species is more likely to survive.
A large population is also important in limiting the risks of environmental influence - as changes may not reach or affect the entire population.
Variation in a species gene pool contributes to its survival in a constantly changing environment through the variance in traits. This is is what is referred to as genetic diversity.Ê
That is because some will have traits that allow them to survive in the new conditions, and those will be able to be passed on by the survivors.
Environmental changes almost demand variation in organisms so that the best fitted to the changing environment survive and reproduce in a greater number. Asexual reproduction produces clones with little to no genetic variation. Good enough for a static environment, but in a challenging environment with no variation that could be more beneficial than cloning the asexual species could find itself selected against.
unstable, fluctuating, adapting, evolving, chaotic,
Hats off to Sir Charles Darwin for his theory of evolution! Variations are very important to species. Some of the variations are more suitable for the species to survive. You get new species with time by selection of the better ones.
Changing their external environment
adapting is like getting used to, but modifying is changing the environment based on your specific needs
constantly changing
A fluid environment is one that is constantly changing.
constantly changing
Genetic variation allows a population to adapt to a changing environment.
constantly changing changes often an evironment

Become extinct over time
because there is not enough variation within the species to allow it to evolve to the changing environment :)
An organism highly adapted to its climate will continue to evolve over millenia as its environment is constantly changing
feedback
If that variation is selected on the basis of survivability and reproductive success then the populations gene pool allele frequency changes and the population becomes better adapted to the immediate environment, or adapted to a new and changing environment.
The atmosphere is constantly changing because of pollution and global warming.
