Question

2 - population ecology: exponential versus logistic growth models
learning objective: differentiate between exponential and logistic population growth models.
which of the following characteristics is representative of the logistic population growth model?
a.) when extended over time, the graph resembles a \j\ shape.
b.) changes in birth and death rates determine the slope.
c.) this model studies population growth without limiting factors.
d.) this model considers limiting factors such as rainfall and food.

Explanation:

The logistic population growth model takes into account environmental - limiting factors like rainfall and food availability. Exponential growth is unrestricted and has a J - shaped curve, while logistic growth is restricted by carrying capacity and has an S - shaped curve. Birth and death rates affect both models, but the key difference is the consideration of limiting factors in logistic growth.

Answer:

d. This model considers limiting factors such as rainfall and food.
