Final answer:
It is true that mathematical models are used to analyze population rates, with population ecologists employing models like exponential and logistic growth to forecast population changes.
Step-by-step explanation:
Mathematical models are indeed used in analyzing population rates, making the statement true. Biologists, particularly population ecologists, apply mathematical methods to data from real or simulated populations to predict changes and trends in population over time. Two fundamental types of population growth models utilized are exponential growth and logistic growth. Exponential growth describes populations that grow without limits, while logistic growth includes factors that restrict growth as the population size increases. While these models don't fully capture the complexities of natural populations, they offer a framework for highlighting trends and making predictions about population dynamics.
