Question 1:
Which of the following is a density-dependent factor that affects population size?
Explanation: The correct answer is C) Predation. Predation is a density-dependent factor that affects population size. As the population density increases, predators may have an easier time finding and consuming prey, leading to a decrease in prey population size.
Question 2:
Which of the following is an example of a density-independent factor that affects population size?
Explanation: The correct answer is D) Drought. Drought is an example of a density-independent factor that affects population size. It can lead to reduced water availability and affect the survival and reproduction of individuals, regardless of population density.
Question 3:
Which of the following is a biotic factor that can affect population size?
Explanation: The correct answer is C) Predation. Predation is a biotic factor that can affect population size. The presence of predators can limit the population size by preying on individuals and regulating their numbers.
Question 4:
Which of the following is an example of an abiotic factor that can affect population size?
Explanation: The correct answer is D) Temperature. Temperature is an example of an abiotic factor that can affect population size. Extreme temperatures can impact the survival and reproduction of individuals, which in turn affects population growth and size.
Question 5:
Which of the following factors is not typically considered a density-dependent factor?
Explanation: The correct answer is D) Habitat destruction. Habitat destruction is not typically considered a density-dependent factor. It directly reduces the available habitat for a population, but its impact is not directly related to population density.
