[고2] 2025 09월 – 41~42번: 동물의 에너지 저장 방식인 체지방 축적과 식량 비축의 장단점

 

Many animals pursue a mixed strategy of accumulating both body fat and food, which leads one to ask, "What are the relative advantages and disadvantages of these two forms of energy storage?" Maximum fat deposition increases with body mass whereas maximum food storage is not constrained by body size. This means that animals, especially small animals, can accumulate much greater energy reserves in the form of stored food than they can in the form of body fat. Further, stored food is more economical than body fat because fat contributes to body mass, and metabolic rate increases with body mass. In other words, there is a metabolic expense to maintaining fat. Excessive fat accumulations may also have a negative effect on an animal's ability to avoid predators. And, if maintaining a high body temperature is advantageous, animals might be expected to accumulate more energy in the form of a food store than as body fat. On the other hand, stored food may rot over time, may be removed by robbers, or may simply be lost. Many animals must expend energy managing and protecting their food stores. Eating food and converting it to fat avoids these types of losses and the energetic costs of managing stored food. A large accumulation of body fat adds to an animal's fasting capacity, especially large animals, permitting some animals to enter prolonged dormancy in the relative security of a hibernaculum. Thus, both fat accumulation and food storage have some decided advantages.

	내용	문제 지문
문제 제기	동물들은 체지방과 먹이 저장을 동시에 하는데, 각각의 장단점이 무엇인지 묻는다	Many animals pursue a mixed strategy of accumulating both body fat and food, which leads one to ask, "What are the relative advantages and disadvantages of these two forms of energy storage?"
근거	체지방은 몸집이 클수록 더 많이 쌓을 수 있지만, 먹이 저장은 크기에 제한이 없다	Maximum fat deposition increases with body mass whereas maximum food storage is not constrained by body size. This means that animals, especially small animals, can accumulate much greater energy reserves in the form of stored food than they can in the form of body fat.
근거	먹이 저장은 체지방보다 경제적이며, 과도한 지방은 대사 부담과 포식자 회피에 불리하다	Further, stored food is more economical than body fat because fat contributes to body mass, and metabolic rate increases with body mass. In other words, there is a metabolic expense to maintaining fat. Excessive fat accumulations may also have a negative effect on an animal's ability to avoid predators.
예시	고체온 유지가 필요할 때는 먹이 저장이 더 유리하지만, 먹이는 상하거나 도난당하거나 잃어버릴 수 있다	And, if maintaining a high body temperature is advantageous, animals might be expected to accumulate more energy in the form of a food store than as body fat. On the other hand, stored food may rot over time, may be removed by robbers, or may simply be lost. Many animals must expend energy managing and protecting their food stores.
결론	지방은 손실 위험이 없고 동면을 가능하게 하며, 결국 지방 축적과 먹이 저장은 각각의 장점이 있다	Eating food and converting it to fat avoids these types of losses and the energetic costs of managing stored food. A large accumulation of body fat adds to an animal's fasting capacity, especially large animals, permitting some animals to enter prolonged dormancy in the relative security of a hibernaculum. Thus, both fat accumulation and food storage have some decided advantages.
