The diagram shows the amount of phosphorus measured in teragrams (1 teragram = 1×10^12) grams), in the various reservoirs of the phosphorus cycle. which of the following is the best explanation for why there is such a small amount of phosphorus that moves into aquatic systems? 1. phosphorus is highly stable in the atmosphere and remains there for long periods of time.2. the amount of phosphorus in the cycle has been greatly reduced because of the use of catalytic converters in automobiles.3. there is not a gaseous phase of the phosphorus cycle, and therefore the movement of phosphorus into oceanic reservoirs is very slow.4. the phosphorus cycle occurs so rapidly that it does not exist in any one reservoir for a very long time.
