  In this paper, we prove that the null space of a weighted composition
operator on $\ell_p~ (1 \leq p < \infty)$ is a complemented subspace. We also
give a necessary and sufficient condition for a weighted composition operator
on $\ell_p$ whose range space is of finite co-dimension. Thereafter, we
characterize a class of weighted composition operators whose range space is a
complemented subspace. Lastly, we characterize weighted composition operators
on $\ell_p$ which are Fredholm operators.
