However, of all the elements recycled in the biosphere, phosphorus is the scarcest and, therefore, the one most limiting in any given ecological system. It is indispensable to life, being intimately involved in energy transfer and in the passage of genetic information in the DNA of all cells. The ultimate source of phosphorus is rock, from which it is released by weathering, leaching, and mining.

The oceans for water and rocks for phosphorous). , the atmosphere; a cloud). The length of time a chemical is held in an exchange pool or a reservoir is termed its residence time. The biotic community includes all living organisms. This community may serve as an exchange pool (although for some chemicals like carbon that can be bound in certain tree species for a thousand years, it may seem more like a reservoir), and it **~hakes~eare's description of Richard-the Kingmaker during the Wars of the Roses.

23 It is interesting to note that even in many natural channel sections of a stream course that appear straight, meandering occurs in the line of maximum water or channel depth (known as the thalweg). A stream renews itself by meandering. Streams wash plants and soil from the land into their waters, and these serve as nutrients for the plants in the rivers. If rivers aren't allowed to meander, if they are channelized, the amount of life they can support will gradually decrease. 2). 2).
