Chapter 53, Problem 17TYU
Summary Introduction
To determine: The country with greater population density among Country N and Country U. The population of Country N in 2017 was 17.1 million and a land area of 15,768 square miles and that of Country U was 325.4 million, and its land area is 3,717,796 square miles.
Introduction: Population density measures the number of individuals within a given area. It is a quantitative measurement of the population of people in accordance with per unit area.

Use the information provided:
population experiences density-dependent growth
K or carrying capacity is 180
r = 0.032 individual/month
1. Calculate how many bugs are added to the population next month when population size is 65?
2. Now keeping the condition of density dependent growth, let's change some numbers: K=270 and r=0.13. If the current population is 125 bugs, how large will the population be in 12 months?

- According to Worldometers, in late November, 2018, the U.S. population was 327,726,061 and the world population was estimated at 7,666,602,725. Considering those numbers, do you think the United States is in a population crisis? Do we have enough land and resources to support a continuous increase in population? Should we, as a nation, concentrate on controlling our population or controlling resource use? Why, or why not?arrow_forwardOpen the Excel Spreadsheet: ACTIVITY Population Biology Data Analysis Perform data analysis for: Cockroach Find the "r" value for Cockroach.

Over the years, the winter coloration (the color of the rabbit's fur) of the surviving rabbit population changed. The graph shows the change in winter coloration of rabbits between 185 to 2000. Based on the data, we could hypothesize that A) the winters are longer in length. B) the snowshoe rabbit has migrated to another area. the amount of snow cover varied over the years. D) more snowshoe rabbit predators have moved into Manitoba. % Populationarrow_forwardYou are an ecologist studyiìng movement behavior of a bird population. You attach radio-transmitters to each member of several different populations of the bird, allowing you to measure precisely how many birds emigrate from each of the populations each year. You gather the following data: Bird population size 712 Total number of birds emigrating per year 163 27 244 68 71 20 642 186 12 389 93 Does emigration represent a density-dependent process in this population?
