What type of growth is shown in the diagram?

• exponential growth
• logistic growth 
• predator-prey cycle
• boom-bust curve

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

• carrying capacity
• population crash
• lag phase
• mutualism

What do you call a period of rapid growth?

• predator-prey cycle

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

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

What is the carrying capacity for this sheep population?

• 1.8 million
• 1.25 million
• 1.6 million
• 1.o million

Type of growth that occurs when disease and parasites are present...

• exponential
• J-shaped
• predator-prey
• logistic

What is the carrying capacity of this population?

• 100
• 200
• 300
• 400

Why has the population been able to grow so quickly in such a short period of time?

• Doctors have developed easier and safer ways to have babies
• People needed more help to work their farms so they had more children
• Because people stayed in one place and only moved when crowded out
• Because of medical care, clean water and better access to nutritious food

• The bird population would infinitely increase
• The bird population would decrease

What point on the graph represents the carrying capacity?

• A
• B
• C
• D
