**Question 7: Future Projection of Survivorship Curves***Discussion Prompt*Consider how survivorship curves, which illustrate the number of individuals surviving at each age for a given species, might evolve over the next 50 years. Reflect on potential factors such as advancements in healthcare, environmental changes, and societal shifts. Do you anticipate significant changes in these curves? Why or why not? Discuss the possible implications and support your reasoning with evidence or theories. This prompt invites thoughtful engagement with demographic and ecological concepts, encouraging students to apply predictive reasoning and critical thinking skills.

A survivorship curve is a graph that measures the proportion of individuals of a particular species…
