We study two variants of P colonies with dynamic environment changing due to an underlying 0L scheme: P colonies with two objects inside each agent that can only consume objects, and P colonies with one object inside each agent which uses rewriting and communication rules. We show that the first kind of P colonies with one consumer agent can generate all sets of natural numbers computed by partially blind register machines. The second kind of P colonies with two agents with rewriting/communication rules is computationally complete. Finally, we demonstrate that P colonies with one such agent with checking programs can simulate catalytic P systems with one catalyst, and consequently, another relation to partially blind register machines is established.
