What is the main reason why the meadows and forests of the eastern United States are not literally hopping with rabbits and toads?
What is the main reason why the meadows and forests of the eastern United States are not literally hopping with rabbits and toads?
- The overpopulation of predators such as hawks and snakes in these areas.
- The absence of suitable habitat for rabbits and toads to thrive.
- The scarcity of water bodies for toads to lay their eggs.
- The presence of limiting factors such as food, shelter, breeding sites, and predators. (correct)
What do cottontail rabbits and American toads have in common with regards to their survival?
What do cottontail rabbits and American toads have in common with regards to their survival?
- Both are immune to most of the density-dependent factors that limit other animal populations.
- Both have a natural ability to defend themselves against predators like hawks and snakes.
- Both require specific resources such as food, water, and suitable habitats to survive and reproduce. (correct)
- Both can reproduce at a much faster rate than other animals in the eastern United States.
What is the distinction between density-dependent factors and density-independent factors?
What is the distinction between density-dependent factors and density-independent factors?
- Density-dependent factors include predators and diseases, while density-independent factors include food availability and breeding sites.
- Density-dependent factors have an impact on the population regardless of its size, while density-independent factors are influenced by the population's size.
- Density-dependent factors are affected by climatic conditions, while density-independent factors are related to biotic interactions.
- Density-dependent factors are influenced by the number of individuals in a population, while density-independent factors are unrelated to population size. (correct)
