old man require less energy giving food than a child​

Answer 1

Answer:

This is because men tend to be larger and have a higher proportion of muscle. The amount of energy you need each day depends on your age, height, and how active you are. But as you tend to lose muscle mass, and activity levels tend to drop with age, kilojoules also need to reduce

Answer 2

A child is more active and at a growing age due to which they need more energy giving food.

Explanation:

1. Old people are already in the stages of their life where they cannot grow anymore. Therefore, they do not need nutrition for physical growth but only mental development and survival.
2. On contrary, a child is in the stage where his body is growing physically as well as mentally.
3. Moreover, an old person is physically weak due to which they do not move or indulge in heavy physical activities while children are very active and always on their foot.
4. Therefore, children need more energy giving food to ensure that their body has enough energy for ensuring growth as well as physical activities.
