new kelp growth Kelp Biomasse kelp detritus and grazing +019 +0,031 +.01 Urchin pop- ulation, A stock-flow diagram for a kelp foresto, at a particular equilbrium is shown above. The Urchin population U is treated as a parameter. The strength of each control is given (in the units per week or 1). weeks Calculate the strength of the overall feedback at this equilibrium and determine whether the equilibrium is stable or unstable. new kelp growth Kelp Biomasse kelp detritus and grazing +019 +0,031 +.01 Urchin pop- ulation, A stock-flow diagram for a kelp foresto, at a particular equilbrium is shown above.
