All living things need energy for their daily activities. For example, birds can y, bees can
produce honey, plants grow and sh can swim because of the energy they have. Even
some non-living things need energy to function. For example, buses need energy to move
and torches need energy to light.
We get energy from the food that we eat. Without energy we cannot do anything.
So, energy is very important for both living and non-living things.
In this unit you will learn about (i) sources of energy, (ii) forms of energy and
(iii) the uses of energy by living and non-living things.
