Final answer:
True, a logistical growth curve depicts a population that grows exponentially at first then levels off as it nears the carrying capacity, resulting in an S-shaped curve.
Step-by-step explanation:
If a country has a logistical growth curve, it is true that the population grows exponentially and then levels off near the carrying capacity.
When resources are unlimited, populations exhibit exponential growth, where the number of individuals can double at a consistent rate over time, which is shown as a J-shaped curve.
As the population increases and resources become limited, the growth rate starts to slow and eventually levels off, forming an S-shaped curve.
This kind of growth is known as logistic growth, and it occurs because the environment can only sustain a certain number of individuals, known as the carrying capacity.
Logistic growth occurs when a population grows exponentially at first and then levels off near the carrying capacity of its environment. Initially, the population growth is rapid and resembles exponential growth, but as resources become limited, the growth rate slows down. Eventually, the growth rate levels off as the population reaches its carrying capacity.
An example of logistic growth is yeast growth in a test tube. Yeast population initially grows rapidly but levels off as it depletes the nutrients necessary for its growth.
Logistic growth is represented by an S-shaped curve on a graph and is a more realistic model of population growth than exponential growth.
