What typically happens to pioneer organisms after new colonizers become established in an ecosystem during ecological succession?

Consider the competitive dynamics: As new colonizers arrive, they often have adaptations that allow them to thrive in the improved conditions created by the pioneer organisms. These new species may outcompete the pioneer organisms for resources such as light, nutrients, and space.

Understand the replacement process: Over time, the pioneer organisms are often replaced by the new colonizers, which are better suited to the changed environment. This is a natural part of ecological succession and leads to the development of a more complex and stable ecosystem.
