  Using Brownian dynamics simulations, the motion of active Brownian particles
(ABPs) in the presence of fuel (or 'food') sources is studied. It is an
established fact that within confined stationary systems, the activity of ABPs
generates density profiles that are enhanced in regions of low activity, which
is generally referred to as 'anti-chemotaxis'. We demonstrate that -- contrary
to common believes -- in non-stationary setups, emerging here as a result of
short fuel bursts, our model ABPs do instead exhibit signatures of chemotactic
behavior. In direct competition with inactive, but otherwise identical Brownian
particles (BPs), the ABPs are shown to fetch a larger amount of food. From a
biological perspective, the ability to turn active would, despite of the
absence of sensoric devices, encompass an evolutionary advantage.
