Holism is a view or approach that one can not understand or predict completely about an individual organism from the knowledge about some of its components.
According to this approach that it is better as a whole than the, some of it parts. However, holism is the various meanings according to the context. It is an ecology concept.
Holism is a theory which suggests that parts of the organism are connected, these cannot function independently but as a part of whole organism.
This can be understood as organism as whole is greater than the sum of its parts.
Thus everything about an organism can be understood through the components that is if a person is suffering from brain disease then this may affect the control and coordination of the body this is likely to affect the whole organism.
