The comprehensive review (in 'Marine Ecology', Wiley & Sons) is of great importance to marine scientists.

The principle that energy does not cycle in ecosys- tems is examined by path and flow analyses of a small, steady state, energy model of an oyster reef community. Path numbers increase combinatorially without bound as path length increases, at much faster rates with energy storage than without. Energy flows over only very short paths in the nonstorage case, but with storage present most flow is associated with long paths.
