A method of constructing asynchronous cellular automata (ACA model) as a parallel composition of two interacting ACA is presented. The resulting ACA is intended to simulate a process with more than one species being involved in it. Two cases of such a composition are considered: (1) when one component of the composition is functioning independently affecting the evolution of the other, and (2) when both components evolute interacting at each iteration. The method is illustrated by simulation of two typical examples: (1) pattern formation process with inhibitor strength changing in time and space, and (2) preypredator interactions proceeding to a stable spacial distribution.
