Populations

What growth pattern describes a population whose growth rate slows or stops following a period of exponential growth?

• logistic growth
• population growth
• exponential growth
• predator-prey cycle

Largest number of individuals of a population that the environment can support...  

• carrying capacity
• population crash
• lag phase
• mutualism

Which type of growth is best illustrated by this rabbit population?

• exponential
• logistic
• S-shaped
• predator-prey

What point on the graph represents the carrying capacity?

• A
• B
• C
• D

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

In a forest ecosystem, which of the following is the best example of a limiting factor for a rabbit population?
