Quiz on Predator-Prey Relationship 1. What is a fundamental characteristic of predator-prey relationships? A. They are stable and do not inﬂuence population dynamics. B. They are irrelevant to ecosystem stability. C. They involve one species (predator) consuming another (prey). D. They only occur in aquatic ecosystems. Answer: They involve one species (predator) consuming another (prey). (C) Predator-prey relationships are essential interactions that signiﬁcantly inﬂuence both population dynamics and ecosystem stability. 2. Which factor can directly affect the population dynamics of predator and prey? A. The feeding habits of herbivores. B. The color of the prey species. C. Resource availability in the environment. D. The maximum lifespan of the predator . Answer: Resource availability in the environment. (C) Resource availability plays a crucial role in the numbers of both predator and prey species. 3. Which of the following is a technique used by predators to catch prey? A. Photosynthesis. B. Competing for resources. 2 C. Ambush. D. Mimicry. Answer: Ambush. (C) Ambush is one of the various hunting strategies employed by predators to capture prey. 4. What does the term 'carrying capacity' refer to in an ecosystem? A. The total biomass of all species present. B. The rate at which species can reproduce. C. The maximum population size a given environment can sustain. D. The number of species in the ecosystem. Answer: The maximum population size a given environment can sustain. (C) Carrying capacity is deﬁned as the maximum population size that the environment can support sustainably. 5. Which model illustrates the cyclical nature of predator-prey interactions? A. Ecosystem Dynamics Model. B. Niche Theory Model. C. Carrying Capacity Model. D. Lotka-Volterra Model. Answer: Lotka-Volterra Model. (D) The Lotka-Volterra Model provides a framework for understanding the cyclical relationship between predator and prey populations. 6. What is one of the limitations of the Lotka-Volterra model? 3 A. It includes interactions with multiple species. B. It accounts for varied environmental changes. C. It assumes a constant environment. D. It provides complex mathematical predictions. Answer: It assumes a constant environment. (C) One limitation of the Lotka-Volterra model is its assumption of a constant environment, ignoring various ecological factors. 7. Which mechanism refers to competition for limited resources between species? A. Trophic cascades. B. Symbiotic relationships. C. Direct interactions. D. Exploitation competition. Answer: Exploitation competition. (D) Exploitation competition occurs when one species consumes resources that other species require, impacting their populations. 8. How do predator-prey relationships contribute to ecosystem stability? A. By minimizing the number of predators. B. By promoting biodiversity and population regulation. C. By eliminating weaker prey species. D. By increasing competition among all species. Answer: By promoting biodiversity and population regulation. (B) Predator-prey relationships are crucial for maintaining biodiversity and 4 regulating populations within ecosystems.
