Scaling Laws in Ecological Webs:
1-Species Scaling law: the basal ( detritus and autothrops), intermediate
( preying on others and themselves preyed upon), and top ( having no
predators) fractions of species do not vary with the total number of
species (S) in the web.
2-Link Scaling Law: The fractions of top-intermediate,top-basal,
intermediate-intermediate, and intermediate-basal links do not vary with
S.
3-Link-Species Scaling Law: The total number of links (L) is proportional
to S and that linkage density (d= L/S) does not vary with S.
