Answer:
This statement is false.
Step-by-step explanation:
Producers (namely mosses and liches) are the first organisms to reenter an ecosystem and are known as "pioneer species". They are proceeded by (in this order) small plants, shrubs, bushes, and climax communities (i.e. large trees). Only then do consumers once again become part of the ecosystem. For all of these reasons, the statement presented in this question is false.
