It is well known that reaction rates can be strongly affected by the
ambient fluid flow. The phenomenon where reaction rates in biology
can be influenced by chemical attraction of species appears to be much less studied. I will consider a simple model involving diffusion, advection, chemotaxis, and absorbing reaction, motivated by the modelling of coral life cycle. We prove that in the framework of this model, chemotaxis plays a crucial role in enhancing reaction rates.
