Question

match each statement to the growth model it best describes.
occurs when resources are essentially unlimited and the number of reproductive individuals increases
growth rate stays roughly constant over time
occurs when the number of reproductive individuals doesnt change
occurs when resources are limited
growth rate initially increases over time but then decreases and eventually reaches zero
growth rate continues increasing over time
linear growth
exponential growth
logistic growth

Explanation:

Step1: Recall Linear Growth Characteristics

Linear growth has a constant growth rate over time. So the statements matching linear growth are "Growth rate stays roughly constant over time" and "Occurs when the number of reproductive individuals doesn't change" (since the growth rate is constant, the number of reproductive individuals doesn't change to maintain that constant rate).

Step2: Recall Exponential Growth Characteristics

Exponential growth occurs when resources are essentially unlimited, so the number of reproductive individuals increases, and the growth rate continues increasing over time (because with unlimited resources, each new individual can reproduce, leading to a multiplicative growth effect). So the statements for exponential growth are "Occurs when resources are essentially unlimited and the number of reproductive individuals increases" and "Growth rate continues increasing over time".

Step3: Recall Logistic Growth Characteristics

Logistic growth occurs when resources are limited. Initially, the population grows (growth rate increases as population size is small and resources are relatively abundant), but as the population approaches the carrying capacity (due to limited resources), the growth rate decreases and eventually reaches zero. So the statements for logistic growth are "Occurs when resources are limited" and "Growth rate initially increases over time but then decreases and eventually reaches zero".

Answer:

• Linear growth: "Growth rate stays roughly constant over time", "Occurs when the number of reproductive individuals doesn't change"
• Exponential growth: "Occurs when resources are essentially unlimited and the number of reproductive individuals increases", "Growth rate continues increasing over time"
• Logistic growth: "Occurs when resources are limited", "Growth rate initially increases over time but then decreases and eventually reaches zero"
