What is Biology ?
Biology is the study of living organisms of all types. The two main areas of biology are plant biology and animal biology, which includes human biology.
Biology is one of the main three sciences (together with Chemistry and Physics) taught in many UK secondary schools. Many younger children also study biology but may use different names for the subject, depending on what, exactly, they are looking at. For example, one popular area is "Nature Studies".
Biology is a very wide discipline that includes many specific areas, including e.g. Botany, Zoology, Marine Biology, Human Biology, and so on.
