What two values would you need to know to figure out the human population density of your community?
To identify: The values to figure out the population density of a community.
Introduction: The population density may be defined as number of individuals from a specific species living in a specific region per unit area. The two important values through which an individual can figure out the population density are size of the area and number of individuals living in that particular area.
Explanation of Solution
Size of the area and the number of individual living in that area are the two main values which an individual need to know to figure out the population density of a community.
Formula to calculate population density:
The two main values to figure out the population density of a community are land area and number of peoples living in that specific area.

- several years ago wolves were reintroduced in to a national park in North Carolina. Researchers have monitored the populations over the last several years and the per capita growth rate of the population is.5. If the current population size is 100, what equation would you use to determine how large he population will be in ten yearS?

Find the most recent “World Population Data Sheet” under the Data section. Choose two nations to compare with respect to: birth rate, death rate, infant mortality rate, rate of population growth, and/or other data indicators of interest to you. What do these data tell you about the health of the populations of these countries?arrow_forwardIn 1975, the population of Peary caribou among the Arctic islands was around 28 000. In 1976, there were 1600 deaths and 900 births, and no immigration or emigration. Calculate the population change as a percentage. Show your work.arrow_forward
- How would you describe human population growth for the past 200 years. When determining Earth’s carrying capacity for humans, why is it not enough to just consider human numbers? What will happen if there is a rapid growth in human population? What solutions do you have in mind to limit the human population growth?arrow_forwardExplain how to estimate the per capita rate of increase in a population. How would you estimate intrinsic rate of increase?arrow_forwardYou will need to complete this question on a separate piece of paper. Scan or take a picture of it and upload the answer. Suppose you have a population of bats growing according to the logistic equation. If the carrying capacity is 400 bats, Demonstrate at which population sizes in relation to K will the population have - a positive growth, negative growth or stable growth. A Create a graph of dN/dt vs N (be sure to label the axes) for this (ii) - Use arrows to population of bats. Indicate on the graph - (i)- k, indicate when the instantaneous rate of change the highest and when is it stable (be sure to label the arrows). B . Provide a brief explanation for why your graph looks the way C that it does.arrow_forward

- Is the wolf population controlled by density or density-independent factors? Explain using one piece of information from the reading to support your choice. You should use those supports to back up your choice, that is, how did this piece of support lead you to your answer.arrow_forwardPRACTICE Calculate the population densities for the following countries. Round to two decimal places. Country: Albania Albanla- Population: 3 002 859 Area: 28 748 km2 Country: Colombia Population: 45 239 079 Colombla Area: 1 138 910 km2arrow_forwardWhich of the following situations describes a population at carrying capacity (K)? Group of answer choices Births + immigrants > deaths + emigrants. Births + immigrants = deaths + emigrants. Births + immigrants < deaths + emigrants.arrow_forward
