Trying one of the followings...
In[209]:=
o = {{0, 1}, {2, 3}, {4, 5}}
Apply[Plus[#1^2 + #2] & , o, {1}]
(Plus[#1[[1]]^2 + #1[[2]]] & ) /@ o
o /. {(x_)?NumberQ, (y_)?NumberQ} -> x^2 + y
MapThread[#1^2 + #2 & , Transpose[o]]
Out[209]=
{{0, 1}, {2, 3}, {4, 5}}
Out[210]=
{1, 7, 21}
Out[211]=
{1, 7, 21}
Out[212]=
{1, 7, 21}
Out[213]=
{1, 7, 21}
