The logistic growth model describes population growth when
resources are constrained. It
is an extension to the exponential growth model that includes an
additional term introducing
the carrying capacity of the habitat.
The differential equation for this model is:
dP/dt=kP(t)(1-P(t)/M)
Where P(t) is the population (or population density) at time t,
k > 0 is a growth constant,
and M is the carrying capacity of the habitat. This...

4. Suppose that the logistic equation dt Pla -bP) models a population of fish in a lake after t months during which no fishing occurs. What is the limiting population for this fish population? suppose that, because of fishing, fish are removed from the lake at a rate proportional to the existing fish population. i. Write a differential equation that describes this situation. ii. Show that if the constant of proportionality for the harvest of fish,...

8. Scientists use the Logistic Growth P.K P(t) = function P. +(K-P.)e FC to model population growth where P. is the population at some reference point, K is the carrying capacity which is a theoretical upper bound of the population and ro is the base growth rate of the population. e.

M 6. The equation for logistic growth has the general form y = 1+ Be-M -M , where M, B, and k are positive constants and M represents the maximum level that y can obtain. Suppose that a lake is stocked with 100 fish. After 3 months there are 250 fish. A study of the ecology of the lake predicts that the lake can support 1000 fish. Find a logistic function for the number NO) of fish in the lake...
