Exponential and Logistic Growth Practice

Front

What is exponential growth?

Back

Rapid increase in quantity or size over time.

Front

Which of the following is an example of exponential growth?

Back

Population of bacteria doubling every hour.

Front

What is growth rate?

Back

Rate at which a population increases over time.

Front

What are population growth models used for?

Back

To study and predict changes in the size and structure of populations over time.

Front

What is logistic growth?

Back

Type of population growth that starts off slow, then accelerates, and eventually levels off.

Front

What is the difference between exponential and logistic growth?

Back

Exponential growth continues to increase rapidly without limits, while logistic growth starts slow, accelerates, and then levels off due to resource limitations.

Front

What factors can affect population growth?

Back

Birth rates, death rates, immigration, emigration, and availability of resources.

Front

What is carrying capacity?

Back

The maximum population size that an environment can sustain indefinitely.

Front

How does competition affect population growth?

Back

Increased competition for resources can limit population growth and lead to a decrease in population size.

Front

What is a J-shaped curve?

Back

A graphical representation of exponential growth, where the population size increases rapidly.
