Bio 270 Practice Population Growth Questions 1 Population Growth Questions Answer Key 1. Distinguish between exponential and logistic population growth. Give the equations for each. Exponential growth is continuous population growth in an environment where resources are unlimited; it is density-independent growth. dN/dt = rN where, dN/dt = change in population size; r = intrinsic rate of increase (= per capita rate of increase and equals birth rate minus death rate); N = population size. Nt = Noert where, Nt = population size at time t; No = original population size, r = intrinsic rate of increase and t = time Logistic growth is continuous population growth in an environment where resources are

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.

Population ecology is the study of populations in relation to environment, including environmental influences on density and distribution, age structure, and population size Concept: Dynamic biological processes influence population density, dispersion, and demographics A population is a group of individuals of a single species living in the same general area Density and Dispersion Density is the number of individuals per unit area or volume Dispersion is the pattern of spacing among individuals within the boundaries of the population Environmental and social factors influence spacing of individuals in a population Density: A Dynamic Perspective In most cases, it is impractical or impossible to count all individuals in a population
