Question

Quizplus · Accepted Answer

In the intertidal zones of California, the diversity of diatoms and algae typically increases initially as these organisms colonize the boulders. However, as succession progresses and the environment becomes more stable and competitive, diversity tends to decline. This pattern reflects the initial colonization and growth phase followed by competitive exclusion and dominance by a few species.
