M4L1 Review

Many fish die due to a drastic change in water temperature.

• Density-Dependent

• Density-Independent

Which of the following is a density-dependent limiting factor?

• human activities

• unusual weather

• competition

• natural disaster

Which of the following is a density-independent limiting factor?

• natural disaster
• predation
• disease
• parasitism

Which of the following is true about density-dependent and density-independent limiting factors?

• The larger a population, the bigger impact a density-dependent limiting factor will have.

• Density-dependent factors include food, water, and space.

• Density- independent factors include natural disasters (extreme weather), seasonal changes and pollution.

• All of the above are true

How are density-dependent and density-independent limiting factors similar?

• They are both environmental factors that restrict the growth of populations.

• They both help increase all populations.

• They both have no effect on population size.

• They both cause exponential growth.

COVID-19 would be classified as a density ___________ factor.

• dependent

• independent

What is the carrying capacity of the graph?

• around 500
• more than 500
• less than 500
• around 600

What is the carrying capacity of the following graph?

• 1000
• 8000
• 800
• 600

The total number of individuals a habitat can survive with the resources it has available.

• Carrying capacity
• Limiting factors
• Resources
• Population

If the amount of food or resources available increases, the carrying capacity for an animal:

• Stays the same
• Increases
• Decreases
• Fluctuates
