Suppose that a population of hacteria grows according to the logistic differential equation dP =0.01P-0.0002P2 dt where Pis the population measured in thousands and t is time measured in days. Logistic growth differential equations are often quite difficult to solve. Instead, you will analyze its direction field to acquire infom ation about the solutions to this differential equation. a) Calculate the maximum population M that the sumounding environment can austain. (Note this is also calked the "canying capacity"). Hint: Rewrite...

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...

A particular bird species found in a certain region is subject to typical density-dependent (logistic) population growth. If the birth rate declines with increasing N according to the function birth rate b= -0.003N+3.4 and death rate increases with N according to the function d=.001N + 0.4. What is the maximum rate of growth, ‘rm’ for this population and find out the carrying capacity of this species, if the initial population size is 1800?
