5. Ecological succession is the process by which the structure of a biological community evolves over time, often following a disturbance, leading to a more stable and diverse ecosystem.
6. The general name for the first species to grow after a volcanic eruption covers an area with lava is a pioneer species.
7. Soil forms from bare rock through weathering, which breaks down the rock into smaller particles, and the addition of organic matter from decomposing plants and animals over time.
8. After a forest fire, succession occurs as new plants grow from seeds or roots that survived the fire, and the ecosystem gradually regains its complexity and biodiversity.
9. Primary succession takes longer than secondary succession because it begins on a barren surface with no soil, requiring the slow formation of soil and the establishment of pioneer species. Secondary succession occurs on a surface where soil already exists, allowing for faster recovery.
10. A community that has reached a stable stage of ecological succession is called a climax community.
