Describe the hierarchy of organization in living organisms.

(N/A) $\rightarrow$ There is a physical (non-living) hierarchy and a biological hierarchy in the organization of a living body.
$\rightarrow$ In the physical hierarchy,various non-living components aggregate to form compounds,which finally enter the living world in the form of cells.
$\rightarrow$ These cells organize to form tissues,which form organs,and several organs combine to form an organ system.
$\rightarrow$ Finally,many organ systems organize to form a living organism.
$\rightarrow$ The properties of tissues are not present in the constituent cells but arise as a result of interactions among the constituent cells.
$\rightarrow$ For example,bone is a hard tissue that provides a framework to the body,but the individual cells present inside it do not possess this property.
$\rightarrow$ This phenomenon of interactions between various components of the body results in the hierarchy of organization.
$\rightarrow$ The various life processes are the result of this interaction and coordination.
