Please if you have the time, I could really use some help :) In a woodland ecosystem, a population of ducks has a carrying capacity of 1,200 ducks, and the maximum rate of increase for this population is 1.0 per individual per year. Using the logistic population growth model for a population of 125 ducks, what is the approximate population growth rate?

10 ducks per year
35 ducks per year
112 ducks per year
140 ducks per year
