Growth Models

What is an example of a density-independent factor affecting population growth?

• Disease outbreaks

• Natural disasters

What is the carrying capacity of an ecosystem?

• The maximum number of individuals that a habitat can support

• The minimum number of individuals that a habitat can support

• The average number of individuals that a habitat can support

• The current number of individuals in a habitat

What is the concept of population density?

• The number of individuals per unit area

• The number of individuals per unit volume

• The number of individuals per unit length

• The number of individuals per unit weight

What is exponential growth in population?

• A linear increase in population over time

• A slow and steady increase in population over time
