Cardinals are birds that do not migrate but spend the winter in New York State. Many people feed these birds sunflower seeds during the winter months. Explain how the starches present in the sunflower seeds help the cardinals to survive. In your answer, be sure to: • identify the building blocks of starches • identify the process used to produce these building blocks • state one way cardinals use these building blocks to survive
