Figure 71. Analog simulations of forcing functions for
Model I and II for five repeating annual cycles, showing
solar radiation (a), present surface water area (b), and
product of-.solar radiation and surface water area (c).

Model I (Model in Figure 10) results: Analog simulations
of fish biomass (a), fish density (b), bird biomass (c),
and bird number (d) under present conditions.

Model II (Model in Figure 10) results: Analog simulations
of fish biomass (a), fish density (b), bird biomass (c),
and bird number (d) under present conditions.
