<span>When you talk about growth, it refers to
development either in size, state or ability, the capacity. Growth in living
organisms are resulted from acquiring nutrients, being able to function in
adaptation, irritability, reproduction and excretion. On contrary, these functions
are absent in nonliving things. When you say growth in nonliving things it’s
either by addition of matter or magnitude. The process is called accretion but
this doesn’t mean maturation or aging in living organisms. Maybe rusting or
oxidation is caused by the chemical change, toxification but not growth just chemical
reaction.  </span>
