Test on Predator-Prey Relationships and Population Ecology
Predator-Prey Relationships and Population Ecology Explained
Test: Predator–prey relationships
20 questions
Question 1: Predators typically cause a reduction in biodiversity by allowing a single prey species to become dominant.
A. Ano
B. Ne
Explanation: The study materials state that predators increase biodiversity because they prevent one species from becoming dominant, rather than causing a reduction by allowing dominance.
Question 2: The provided materials indicate that the owl-mouse relationship is not an example of a predator-prey relationship.
A. Ano
B. Ne
Explanation: The study materials list 'Owl- mice' explicitly as an example under 'Examples: Food webs (illustrations of species interdependence)', which is presented in the context of predator-prey relationships and species interdependence.
Question 3: Is it true that the evolution of predators proceeds independently of the evolution of their prey?
A. Ano
B. Ne
Explanation: Predators and prey evolve together, indicating their evolutionary paths are interdependent.
Question 4: A predator-prey relationship functions as a negative feedback relationship.
A. Ano
B. Ne
Explanation: The study materials explicitly state that a 'Predator prey is an example of a negative feedback relationship'. This dynamic is further illustrated by how an increase in the predator population leads to a decrease in the prey population.
Question 5: Predator-prey relationships demonstrate that all organisms in an ecological system are interdependent.
A. Ano
B. Ne
Explanation: The study materials state, 'All organism are interdependent.' and explicitly discuss how 'Predator prey relationship' is an example of populations affecting each other, with predators regulating prey and changes in one population affecting the other.
