$A$ ball of snow when rolled over snow increases in mass,volume and size. Is this comparable to growth as seen in living organisms? Why?

(N/A) $\rightarrow$ $A$ ball of snow increases in mass,volume,and size when rolled over snow,but this increase is due to the accumulation of material on the surface from the outside (accretion).
$\rightarrow$ In living organisms,growth occurs due to the internal accumulation of materials and the synthesis of new protoplasm through cell division.
$\rightarrow$ Therefore,the growth of a snow ball is not comparable to the growth of living organisms because growth in living beings is intrinsic (from within),whereas in non-living objects like a snow ball,it is extrinsic (from outside).
