Correct Response: C. Total nutrient needs are higher during adolescence than any other time in the lifespan. During puberty, nutrient needs for both males and females increase sharply to keep up with changes in body composition and biology. Caloric needs during infancy, when the body is small, range from about 500 to 800 per day (A). The growing bodies of adolescents require about 2200 calories per day for the average girl and about 3000 for the average boy. In early childhood, bodies are smaller and growth is slower than in the periods of development before and after (B), and by early adulthood growth has slowed or stopped, so caloric needs decline (D).
