Primary vs. Secondary Succession: How Ecosystems Recover Over Time

In today’s lesson, we explore the natural process of succession-how ecosystems recover and grow after being disrupted.
Learn the key differences between primary succession, which starts from bare rock and no life, and secondary succession, where soil and life remain after a disturbance. Discover how pioneer species help build new ecosystems and how life bounces back more quickly in areas with existing soil.
