Question 1: What is a density-dependent limiting factor?
Question 2: When do density-dependent factors operate most strongly?
Question 3: What are four density-dependent limiting factors?
Question 4: What term describes a limiting factor that affects all populations in similar way regardless of population size?
Question 5: What is the usual response in the population size of many species to a density-independent limiting factor?
Question 6: A population continues at a stable size for many years. Suddenly, in a single season, the population size drops by half. Is the cause more likely to be density-dependent, density independent, or both? Explain your answer.
