Test: Predator–prey relationships
20 questions
Question 1: The primary mechanism by which predators affect prey populations is solely through direct competition for resources.
A. Ano
B. Ne
Explanation: Predation involves the predator catching, killing, and eating the prey. Additionally, predators regulate the amount and distribution of prey species, affect biodiversity by preventing one species from becoming dominant, and keep prey species genetically stronger by removing weaker individuals. These are direct impacts and regulatory mechanisms, not solely competition for resources.
Question 2: In the provided examples of predator-prey relationships, mice are identified as the predators of owls.
A. Ano
B. Ne
Explanation: The study materials explicitly list 'Owl- mice' as an example under 'Predator prey relationship' and 'Food webs', indicating the owl as the predator and the mice as the prey.
Question 3: Predators and prey evolve together.
A. Ano
B. Ne
Explanation: The study materials explicitly state that 'Predators and prey evolve together'.
Question 4: The provided materials state that aphids are predators of ladybirds.
A. Ano
B. Ne
Explanation: The study materials list 'Aphid – lady bird' as an example under 'Predator prey relationship' and 'Food webs'. However, they do not specify that aphids are predators of ladybirds. The materials only present this pair as an example of species interdependence, without assigning specific predator/prey roles for this particular example.
Question 5: Predation occurs when a predator catches, kills, and eats its prey.
A. Ano
B. Ne
Explanation: Predation is defined as the process where the predator catches, kills, and eats the prey.
