Study Notes
Ecological succession is the gradual change in an ecosystem through predictable stages. Primary succession starts on bare rock, leading to a complete ecosystem. Secondary succession occurs after a disturbance with intact soil, exemplified by pond succession. Pioneer species initiate ecosystem development, culminating in a stable climax community.
