•Knowing the habitat where the coronavirus thrives, discuss the factors that would influence the population size of SARS-CoV-2.•Describe the process that SARS-CoV-2 uses to multiply (give the details).•Describe how SARS-CoV-2 migrates.•Determine whether the SARS-CoV-2 virus population growth inside its host is controlled by density-dependent or density-independent regulation and explain why.•Discuss how r, b, d, N, and K play a role in the population growth of SARS-CoV-2 within the host.•Discuss how population density of the virus influence the population growth and regulation of the virus.•How does population density of humans influence the spread of SARS-CoV-2 ? Discuss whether the spread of SARS-CoV-2 from host to host is density-dependent or density independent. Explain why social distancing 6ft from one another is recommended based on the reasoning you used here.•Understanding that when one is first infected with SARS-CoV-2 the population size of the virus is low. How might the vaccine influence the population of SARS-CoV-2 when it is a small population. What ecological principle from the chapter might be in effect here?•Is SARS-CoV-2 an example of an r-selected or K-selected species. Explain your answer.
