## Population Problems

AP Biology Population Practice Problems dN/dt = rN = B-D dN/dt = rN(K-N/K) There is a population of tigers that has 100 individuals. In one month, there are 12 births and 22 deaths. Calculate the individual growth rate. A population of 500 mealworms exhibits logistic growth. If the carrying capacity is 450 mealworms and r = 0.1, what is the population growth rate? In other words, how many individuals are added/lost to the population in one generation? You collect the following information during a one-year period. There are at the start of the year 1,000 deer on the island; 120 deer die, 200 deer are born, 20 immigrate, and 10 emigrate. Calculate the growth rate.
