Succession occurs because **a. organisms gradually change the environment**.

This process involves changes in the biological community that can lead to the development of more complex ecosystems over time. As organisms establish themselves, they modify the environment in ways that allow new species to thrive, ultimately leading to a climax community where stable species interactions are established.
