Final answer:
Hawks obtain glucose by consuming other animals that have eaten plants or other herbivores. This energy transfer is part of a food chain that originates with plant photosynthesis. Glucose from food is converted to ATP through cellular respiration in the hawk's body.
Step-by-step explanation:
The hawk obtains the glucose it needs for energy through its diet. Since all glucose is originally produced through photosynthesis by plants, hawks, being carnivores, must consume other animals to get this essential nutrient. For example, a hawk may eat a rabbit that consumed plants, or it might eat a snake that has eaten a rabbit. Through these feeding interactions, the energy and carbohydrates that originated in plants are passed up the food chain to the hawk.
In the hawk's body, the digested materials are converted to glucose and then through a process called cellular respiration, the glucose is broken down to release energy in a form that cells can use, known as ATP (adenosine triphosphate). This energy powers the hawk's flight and other life-sustaining activities.
