• Immigration

Which spot on the graph represents the lag phase, otherwise known as the phase of the graph where the population is first starting to colonize the area? (Click the correct hot spot).

Consider a population of wolves: Which factors would cause the population to INCREASE? Select all that apply.

• Birth Rates > Death Rates

• Birth Rates < Death Rates

• Immigration > Emigration

Which population of organisms is one of the few that has seen exponential growth? (Look to your notes and graphs we have done together!)

• Bears

• Fish

• Rats

• Humans

A population's carrying capacity is defined as...

• Maximum number of individuals the population can support before growth starts to rapidly expand

• Maximum number of individuals in the population the available resources can support before growth is halted

• Maximum number of individuals the population's resources can support before growth is stopped, and starts to rapidly decline

• Minimum number of individuals needed to get a population off the ground to begin growing exponentially

Density dependent factors that limit the size of a population include available space, waste accumulation, competition, etc. How would you define these density dependent factors?

• Factors that depend on the population's size.

• Factors that do not depend on the population's size.

• Factors that limit a populations ability to grow because there are not enough individuals in the population.

• Factors that cause a population to explode in population if left unchecked.

This species classification is usually characterized by exponential growth.

• R-Selected

• K-Selected

The human population has grown exponentially. What does that say about our birth and death rates?

• Birth rates > Death rates

• Birth rates < Death rates

What type of growth is shown in the diagram?

• exponential growth

• logistic growth 

• predator-prey cycle

• boom-bust curve

Answer explanation

The diagram illustrates exponential growth, characterized by a rapid increase in population size over time, typically represented by a J-shaped curve. This is distinct from logistic growth, which levels off as resources become limited.
