Uranium is a possible polluting agent of the natural environment.
It would be referred to as equilibrium. It has never, nor will it ever, be completely achieved.
Something as close to their natural environment as possible.
Environment, natural habitat, and ecosystem are a couple possible synonyms.
They are the top predator in the natural environment and are needed to maintain that environment (in which humans also live) in a healthy state.
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.
There exists a natural equilibrium. It maintains the creation and depletion of ozone.
Sea stars prefer a clean environment with a low salt content. They prefer an abundance of food, and like their environment to be as natural as possible.

The natural dynamic equilibrium of stratospheric ozone involves the continuous creation and destruction of ozone molecules. Ozone is formed when oxygen molecules are broken apart by solar radiation, and it is destroyed by various chemical reactions involving other compounds in the atmosphere. This balance helps maintain a relatively stable ozone concentration in the stratosphere.
