When we walk or ride a bicycle, we are using up energy. Even when we are
not doing any apparent activity, energy is needed to maintain a state of
order in our body. We also need materials from outside in order to grow,
develop, synthesise protein and other substances needed in the body. This
source of energy and materials is the food we eat.
How do living things get their food?
The general requirement for energy and materials is common in all
organisms, but it is fulfilled in different ways. Some organisms use simple
food material obtained from inorganic sources in the form of carbon
dioxide and water. These organisms, the autotrophs, include green plants
and some bacteria. Other organisms utilise complex substances. These
complex substances have to be broken down into simpler ones before they
can be used for the upkeep and growth of the body. To achieve this,
