The following model is used to represent the effect of solar radiation on the photosynthesis rate of aquatic plants where P the photosynthesis rate (mg m 3 d 1 ),P m the maximum photosynthesis rate (mg m 3 d 1 ), I solar radiation (E m 2 s 1 ), and Isat optimal solar radiation (E m 2 s 1 ) Use nonlinear regression to evaluate Pm and Isat based on the following data P Pm 1 e 1 sat al Isat 1

Question: The following model is used to represent the effect of solar radiation on the photosynthesis rate of aquatic plants: where P = the photosynthesis rate

The following model is used to represent the effect of solar radiation on the photosynthesis rate of aquatic plants:

P= Pm 1 -e 1 sat al Isat +1

where P = the photosynthesis rate (mg m⁻³d⁻¹),P_m = the maximum photosynthesis rate (mg m⁻³d⁻¹), I = solar radiation (μE m⁻²s⁻¹), and Isat = optimal solar radiation (μE m⁻²s⁻¹). Use nonlinear regression to evaluate Pm and Isat based on the following data:

P= Pm 1 -e 1 sat al Isat +1
