Zookeepers talk about the diet needed to keep a gorilla and a penguin healthy. A healthy diet gives the animals energy and helps them to recover from illness. Gorillas are vegetarian and eat a large variety of fruit and vegetables. Chestnut is a six-month-old penguin who has been hand-reared. He eats 20 - 30 fish each day and is very hungry and demanding. If the penguin did not eat he would lose body weight, become ill and eventually die.

After conducting work on human nutrition and balanced diets, this clip could be used to initiate an activity for pupils to design healthy menus for different animals. This clip could also be used to discuss how animals who have different diets, such as herbivores, can obtain a balanced diet without eating meat.
