1 Death is a major event not only for the person who dies but also for the microbes that inhabit their body. Which of the following statements best describes why? a. All the microbes that were living inside the person’s body die when the person dies. b. Microbial populations grow and spread to different areas of the body after the person dies. c. Microbes in the body have fewer resources after the person dies, which increases competition

Using what you’ve learned from the video, answer the following questions in the spaces provided.
1 Death is a major event not only for the person who dies but also for the microbes that inhabit their body. Which of the following statements best describes why?
a. All the microbes that were living inside the person’s body die when the person dies.
b. Microbial populations grow and spread to different areas of the body after the person dies.
c. Microbes in the body have fewer
2 Which of the following statements about cadavers (dead bodies) is most likely to be true?
a. Microbial communities in and around a cadaver change over time.
b. Samples taken from different cadavers always contain the same microbes.
c. The microbial community found in a cadaver is very similar to the one found in a living body.
3 After death, gases build up inside the body and cause the skin to rupture (break open). Rupture is a significant event because microbes from outside the body can now access the inside. Which of the following can be a source of the microbes that enter the body after it ruptures? What abiotic factors might affect the kind of scavengers that contribute to a cadaver’s decomposition? Select all that apply.
a. skin
b. air
c. soil
d. insects
4 Describe how the scientists in the video are using microbes to create a tool to estimate the time since death.
5 Blowflies are often the first scavengers to arrive at a cadaver. They lay their eggs in orifices and open wounds, and the stage of their development can help determine time since death. How might the presence of blowflies affect the course of decomposition?
