#### Phyto 2 - Michaelis-Menten curve for phytoplankton

##### Joao G. Ferreira ★

Simple model to illustrate Michaelis-Menten equation for nutrient uptake by phytoplankton.

The equation is:

P = Ppot S / (Ks + S)

Where:

P: Nutrient-limited production (e.g. d-1, or mg C m-2 d-1)

Ppot: Potential production (same units as P)

S: Nutrient concentation (e.g. umol N L-1)

Ks: Half saturation constant for nutrient (same units as S)

The model contains no state variables, just illustrates the rate of production, by making the value of S equal to the timestep (in days). Move the slider to the left for more pronounced hyperbolic response, to the right for linear response.

The equation is:

P = Ppot S / (Ks + S)
