What causes the logistic growth of the size of a population? a. Sufficient food and shelter b. Limits to reproductive growth c. A lack of resource competition d. A significant decrease in population size

The correct answer is **b. Limits to reproductive growth**. Logistic growth occurs when a population grows rapidly initially but then slows down as it approaches the carrying capacity of its environment. This is typically due to limits on resources (such as food, space, and shelter) and increased competition as the population size increases, leading to a stabilization of growth as it reaches the limits imposed by environmental factors.
