<span>The way the organism uses the range of physical and biological conditions in which it lives. </span>
<span>If you place a cucumber in distilled water, it would eventually wither and die, because distilled water has none of the solvents that the cucumber needs to fuel its cells.</span>
The movement of any material from one place to another is a called a flux. Carbon moving from one pool to another would be considered a carbon flux. BY just having some of the pool's essence get into another pool would cause the carbon to be transferred. Such as if someone jumped out of one pool and then jumped into the next.
hope this helps.
