Question

Give technical terna rie graphical represebtation trophic structures in food chain

Answer 1

The traditional method of representing steady-state ecosystem models, usually by scattering interconnected

boxes across a page, underutilizes the potential descriptive and explanatory power of graphical representations.

S?me alternative approaches are proposed: (1) drawing boxes with areas proportional to the logarithms of the

blO~assestheyrepresent, ordered alongthe ordinate in terms oftheirweightedmean trophic levels; (2) plottingboxes

asIn (1) along the ordinate, but using box-specific particle size for ordering along the abscissa (which leads to "sizeshifted" models); and (3) mapping the fluxes between boxes, arranged as in (2), in terms ofisolines.
