Verified step by step guidance

1. Understand the concept of ecological succession, which is the process by which the structure of a biological community evolves over time.
2. Identify the types of ecological succession: primary succession, secondary succession, and climax succession.
3. Primary succession occurs in lifeless areas where there is no soil, such as after a volcanic eruption or glacier retreat. Soil formation is a crucial step before plants can grow.
4. Secondary succession occurs in areas where a disturbance has destroyed a community but left the soil intact, such as after a forest fire.
5. Climax succession refers to a stable community that has reached the final stage of ecological succession, where the ecosystem is in equilibrium.
