Governing equation for primary producer populations<br />
For population i,<br />
dB i /B i dt =[Pm i {h(T) i , f(I) i , g(N) i , hmod i } (1-Presp i )] – Dresp i – S i – M i – G i - Sc i<br />
where,<br />
B i biomass of population i gC/m 2<br />
Pm i maximum photosynthesis rate gC/gC/d<br />
h(T) i temperature dependence unitless<br />
f(I) i light limitation unitless<br />
g(N) i nutrient limitation (N,P,Si) unitless<br />
hmod i habitat quality modifier unitless<br />
Presp i photorespiration unitless<br />
Drespi dark respiration gC/gC/d<br />
S i sinking rate (phytoplankton) gC/m 2 /d<br />
M i mortality rate gC/m 2 /d<br />
G i loss to grazing gC/m 2 /d<br />
