Population Growth Models

• It limits the maximum population size.

• It increases the growth rate.

• It decreases the initial population size.

• It has no effect on population growth.

DOK Level 3: Strategic Thinking

Analyze the population growth of a species in a new environment using both logistical and exponential models. What factors would you consider, and why?

• Initial population size.

• Growth rate.

• Carrying capacity.

• Environmental resistance.

DOK Level 4: Extended Thinking

Develop a comprehensive plan to study the population dynamics of an endangered species. Include logistical and exponential growth models in your analysis.

• Define the objectives of the study.

• Outline the methodology.

• Identify the key variables and data collection methods.

• Discuss how the results will inform conservation efforts.

What kind of growth is shown here, and what is the vocabulary term for the dotted line?

• Logistic growth, accelerating line

• Exponential growth, carrying capacity

• Logistic growth, carrying capacity

• Exponential growth, accelerating line

What is the equation that represents population change over time?

• Growth rate = birth rate * death rate

• Growth rate = birth rate - death rate

• Growth rate = birth rate / death rate

• Growth rate = birth rate + death rate

When a population grows past the ecosystem's carrying capacity, what happens to the population?

• Continues to grow

• The population starts to die off to return to carrying capcity

• The population will go extinct due to lack of resources

• The population grows then finds a new carrying capacity

What is a primary difference between exponential growth and logistic growth of a population?

• Exponential growth is not affected by limiting factors.

• Logistic growth does not consider the environment's carrying capacity.

• Exponential growth can continue indefinitely.

• Logistic growth shows a population decline phase.

DOK Level 2: Skill/Concept

In logistic growth, what happens when a population reaches its carrying capacity?

• The population stops growing completely.

• The population size begins to oscillate around the carrying capacity.

• The population growth rate becomes zero.

• The population declines rapidly.

DOK Level 2: Skill/Concept

The reason that organisms cannot produce populations of unlimited size is that

• Populations always stay exactly the same.

• The resources of Earth are limited.

• There is no carrying capacity for the whole Earth.

• Species rarely compete with each other for food.
