Grazing

Grazing represents the consumption of phytoplankton by zooplankton. This process will be represented by a Michaelis-Menten function with a threshold value of the phytoplankton concentration under which no predation can occur.

The grazing rate will so be the product of a maximum rate and a limitating factor depending on the prey (phytoplankton) concentration :
