10 Questions
What is the main reason why the meadows and forests of the eastern United States are not literally hopping with rabbits and toads?
The presence of limiting factors such as food, shelter, breeding sites, and predators.
What do cottontail rabbits and American toads have in common with regards to their survival?
Both require specific resources such as food, water, and suitable habitats to survive and reproduce.
What is the distinction between density-dependent factors and density-independent factors?
Density-dependent factors are influenced by the number of individuals in a population, while density-independent factors are unrelated to population size.
Why do cottontail rabbits and American toads face potentially deadly dangers despite avoiding predators like hawks and snakes?
They face other potentially deadly dangers such as diseases, forest fires, and drought.
Which of the following factors are considered density-independent limiting factors?
Hurricanes and pollutants
What is an example of a density-dependent limiting factor mentioned in the text?
The boom-and-bust cycle of collared lemming population
What is the impact of adding new nest sites for mountain chickadees, as mentioned in the text?
It causes a significant increase in the nesting population
What happens to the lemming population after the stoat population has had time to grow to greater numbers?
The lemming population crashes
What does it mean when a population has reached the 'carrying capacity' of the ecosystem?
The population growth slows and then stops
Which statement best describes density-independent limiting factors?
They are nonliving factors that affect all populations regardless of density.
