Role of organisms
Introduced substances may be rapidly turned over between water and organisms and effectively removed from the water into organisms. The rapidity of these processes and their effect on water content emphasizes the responsiveness of organisms and communities to the chemistry of environment, and the significance of their effects on the chemistry of environment. Uptake and accumulation by organisms (and settling of dead organisms) are responsible also for the slower, longer-term removal of the introduced substance from the water with its plankton, into other parts of the ecosystem.
