logistic growth model is the model which suggest the growth of a population with respect to the time.
the equation of this growth is given by the formula
where dN/dt is the population growth rate - average growth rate per year
r -maximum percapita growth - maximum average growth rate per year,
K is carrying capacity- the number of individuals that can be feed by environment witnhout affeting the environment itself
N - number of individuals in a population
here N=100
K=500
r=0.1/year
we are asked to find dN/dt
so applying values to equation
dN/dt= 0.1*(500-100)*100/500
=0.1*400*1/5
=40/5
dN/dt = 8 individuals per year

Stochastic Population Growth Model Next, we are going to monitor the population growth of an asexually reproducing single-celled organism, centinia lincolni (pennies). This Centina population has a mortality rate of 50% per year, but all individuals that survive the year divide to produce an additional individual. The very most basic growth model of a closed population is: N+ N-deaths births Rewritten to use rates instead of individuals, this equation becomes: N+ -N,S+N.BS where S is the probability of survival (0.5)...

- ap-bp? This equation is known as the logistic law of population growth and the numbers a, b are called the vital coefficients of the population. It was first introduced in 1837 by the Dutch mathematical-biologist Verhulst. Now, the constant b, in general, will be very small compared to a, so that if p is not too large then the term - bp will be negligible compared to ap and the population will grow exponentially. However, when p is very...
