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.
No. The definition of a species is often defined as the largest group of organisms capable of interbreeding and producing fertile offspring. If several are totally different they don't fit the definition.
The five Hardy-Weinberg principles are:1. No mutations2. No natural selection3. random mating4. a large population5. no immigration or emigrationIt is impossible to have no natural selection in a natural environment because that would require all organisms to be equally fit. The only way to meet this principle is to have a population of genetically identical organisms which does not happen naturally. All five of these principles cannot be met in real life, but it may be possible to have a species in hardy- weinberg equilibrium in a lab situation.
its because that all the organisms get fit in one place.
Photoautotrophs
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.
0 because they do not fit in equally, but if you don't want the equally then 3.
ecology
On average, men and women are equally fit.
