  Modeling foraging via basic models is a problem that has been recently
investigated from several points of view. However, understanding the effect of
the spatial distribution of food on the lifetime of a forager has not been
achieved yet. We explore here how the distribution of food in space affects the
forager's lifetime in several different scenarios. We analyze a random forager
and a smelling forager in both one and two dimensions. We first consider a
general food distribution, and then analyze in detail specific distributions
including constant distance between food, certain probability of existence of
food at each site, and power-law distribution of distances between food. For a
forager in one dimension without smell we find analytically the lifetime, and
for a forager with smell we find the condition for immortality. In two
dimensions we find based on analytical considerations that the lifetime ($T$)
scales with the starving time ($S$) and food density ($f$) as $T\sim
S^4f^{3/2}$.
