Many animals recognize their food because they see it. So do        . When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other         when you choose your food. You may         it because it smells good or because it         good. You may dislike some types of food because they do not look, smell or taste very nice.
Different         use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.
Although there are many         types of food, some animals spend their lives eating only one type. The giant panda eats only one         type of bamboo. Other animals eat only one type of food even when given the       . A kind of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other        in the garden. However, most animals have a more         diet. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The         of these animals will be different depending on the season.
       have a very varied diet. We often eat food because we like it and not because it is       for us. In countries such as France and Britain, people eat foods with too much        . This makes them overweight, which is bad for their health. Eating too much red meat and animal        , such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modem life.
