Energy

As we all know we need energy in our daily life. There are many kinds of energy. We can get our energy from food.

The energy in food comes from sunlight which helps plants grow. Plants store up energy from the sun, much of our food comes from plants. Some of our food comes from animals, but animals depend on plants for food too.
