### Graph Explanation The graph provided illustrates how the birth rate, an essential demographic metric, changes with different population sizes. - **Axes:** - The vertical axis represents the "Birth Rate." - The horizontal axis represents "Population Size (N)." - **Black Line:** - The line varies in slope across three distinct regions marked by gray boxes labeled A, B, and C, indicating how the birth rate changes as a function of population size. - **Regions:** - **Region A:** The birth rate increases with increasing population size. - **Region B:** The birth rate remains constant, indicating stability within this range of population sizes. - **Region C:** The birth rate decreases as the population size continues to increase. ### Terminology and Matching Below the graph, a matching exercise links specific ecological concepts to the regions in the graph: 1. **Negative density-dependence:** Most applicable to **Region C**, where an increase in population size leads to a decrease in birth rate. 2. **Positive density-dependence (Allee effect):** Corresponds to **Region A**, where an increase in population size results in increased birth rate. 3. **Exponential growth:** Best represents **Region B**, where the birth rate remains stable, potentially indicating optimal growth conditions before the negative effects of higher density set in.
