The graph below shows the population of three different families of marine organisms along five different mass extinction events. Each colour on the graph represents a family of organisms, and the Y axis shows how many species belong to that family. a. What stage of population growth is displayed at point ‘0’ on the graph above? b. The Extinction Event that occurred at point 3 was particularly significant. Using the graph, explain how this event impacted each marine family. c. The extinction events mapped above had significant impact on marine life. What type of event could have a similar impact on the human population?
