NO, they r what we call servivol for the fittest and cant all organisms fit their enviromemnt equally there must be weak and strong and cant live in the same place.
They may or may not be equally fit in another environment.
If you don;t fit your environment you either leave or die.
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.
The fit are those organisms in the immediate environment that have the adaptions that allow them to survive and reproduce successfully at a better rate than organisms not so fit.
Adaptation
Organisms that are less fit can die before they reproduce. This is statistically more likely for such organisms. Organisms that are less fit have problems getting mates as they are passed over in greater numbers than fit organisms. Organisms that are less fit can not bring the offspring to term and provide as well for the offspring as fit organisms can. Organisms that are less fit pass on to their progeny the genetic insults that they carry, thus their offspring are less fit also. And many other reasons could be thought of here, so you think of some reasons yourself.
The process of survival of the most reproductively fit organisms is called natural selection. It involves the adaptation of species to their environment through the passing on of favorable traits to future generations.
its because that all the organisms get fit in one place.
0 because they do not fit in equally, but if you don't want the equally then 3.
On average, men and women are equally fit.
Photoautotrophs
the organisms can effectively survive and reproduce to make sure that its genetic traits are passed on. Those that aren't biologically fit are not able to reproduce effectively and eventually their genes pass out of the gene pool.
