Homework Answers
1) Carrying capacity: the maximum number of individuals that a habitat can support indefinitely
2) Logistical growth is density dependent,as you approach carry capacity both a decrease in birth rates and increase in death dates
3) Exponential growth occurs as long as resources are unlimited and a population can double at regular intervals. Logistic growth occurs when resources become strained or limited, and the population levels off.

More Calculating Population Size Populations of any organism can be analyzed mathematically. Population biologists are interested in characteristics such as doubling time, growth rate, carrying capacity, and total population at the end of a given amount of time. These calculations depend on such variables as birth and death rate, immigration and emigration, and initial population size. Use the following formulas to find the population size for each of the...

The carrying capacity (K) is the maximum population size that can be supported or sustained by a given environment. Which of the following statements about the carrying capacity is NOT true? a. When a population overshoots K, individuals die due to lack of resources. b. Once a population reaches its carrying capacity, the size of the population remains constant. c. Environmental fluctuations cause the carrying capacity to fluctuate over time. d. We can think of K as some "average" value...

The initial population of A city is 40000. In a year, the birth and death rates of this city are 0.7 and 0.55, respectively. There is a series migration problem from city B to city A with 0.3 rate every 2 years. The maximum carrying capacity of this city is 90000. Model the population of growth for the city A in Simulink. a) What is the number of people after 8.5 years in City A? b) How many years later...

a) You are studying a population of aphids with an initial
population size of 500. During a one-month period, you observe 40
births and 15 deaths in the population. Estimate the value of r for
that month, and predict the population size in three months (from
the initial population size). Remember that r is the per capita
rate of population increase. (Assume exponential population
growth).
b) Imagine you are growing ciliates in a laboratory flask. The
