Quiz on heterotrophs 1. What adaptation might help a heterotroph to acquire food more eﬃciently? A. Static digestive systems B. Specialized teeth or beaks C. Slower locomotion D. Reduced sensory perception Answer: Specialized teeth or beaks (B) Specialized teeth or beaks allow heterotrophs to effectively grasp and process their food. 2. How do human activities impact heterotrophic populations? A. Increasing their habitat diversity B. Enhancing their food sources C. Facilitating their migration D. Leading to habitat destruction Answer: Leading to habitat destruction (D) Habitat destruction from human activities results in lowered diversity and population declines among heterotrophs. 3. Which of the following traits is favored by natural selection in heterotrophs? A. Traits enhancing food acquisition B. Static resource utilization methods C. Traits that hinder food processing 2 D. Generic adaptations across environments Answer: Traits enhancing food acquisition (A) Natural selection promotes traits that provide advantages in acquiring and processing food eﬃciently. 4. What role do specialized digestive systems and enzymes play in heterotrophs? A. They cause food to be rejected by the body. B. They limit food choices to one type. C. They enable eﬃcient breakdown of various foods. D. They increase the time taken to digest food. Answer: They enable eﬃcient breakdown of various foods. (C) Specialized digestive systems and enzymes allow heterotrophs to eﬃciently digest a variety of food sources. 5. What outcome can result from the overexploitation of heterotrophic species? A. Extinction or endangerment of species B. Stabilization of predator-prey relationships C. Increased ecological balance D. Enhanced genetic diversity Answer: Extinction or endangerment of species (A) Overexploitation of heterotrophic species can lead to their extinction or make them endangered. 3
