A
Cyclic growth
B
Exponential growth
C
Logistic growth
D
Linear growth
Verified step by step guidance
1
Step 1: Begin by analyzing the graph described in the problem. The population size increases rapidly at first and then levels off as it approaches a maximum limit. This leveling off indicates that the population is reaching a carrying capacity, which is a key feature of logistic growth.
Step 2: Understand the concept of logistic growth. Logistic growth occurs when a population grows rapidly at first due to abundant resources but slows down as resources become limited, eventually stabilizing at the carrying capacity. The equation for logistic growth is often expressed as: , where is the population size, is the intrinsic growth rate, and is the carrying capacity.
Step 3: Compare logistic growth to other types of population growth mentioned in the problem. Cyclic growth involves populations fluctuating in a repeating pattern, exponential growth involves continuous rapid growth without leveling off, and linear growth involves a constant rate of increase. None of these match the pattern described in the graph.
Step 4: Recognize that the graph's pattern aligns with logistic growth because it includes an initial rapid increase followed by stabilization at a maximum limit, which is the carrying capacity.
Step 5: Conclude that the correct answer is logistic growth, as it best describes the population dynamics shown in the graph.
