Which of the following best summarizes the study of sunflower sea stars' feeding behavior when presented with nutritionally varied prey?

• A. They exclusively chase nutritionally poor prey
• B. They will eat any prey regardless of nutrition
• C. They are capable of hunting sea urchins and may prefer other nutritious prey
• D. They rely on predators to obtain prey

Answer: (C)

Understanding this question hinges on how predators choose prey based on nutritional value. Sunflower sea stars are generalist predators that can capture and eat a range of prey, including sea urchins. When prey vary in nutritional quality, it makes sense for them to favor more nutritious options while still being able to feed on sea urchins. So, the best summary is that they are capable of hunting sea urchins and may prefer other nutritious prey. This fits with the idea of selective feeding driven by energy gain, rather than indiscriminate eating or relying on others to obtain prey.
