  1. Succession in Ecosystems Mrs. Karim

  2. Succession- • a gradual changes in a community over a period of time. new populations of organisms gradually replace existing ones • There are three different stages to succession: • Primary succession • Secondary succession • Climax Community

  3. Primary succession- • Life start forming in rocks, no Soil. Examples: • – Lichens grow bare rock

  4. Primary succession- • New bare rock comes from 2 sources: • 1. volcanic lava flow cools and forms rock

  5. Primary succession- And the other source of rocks • 2. Glaciers retreat and expose rock

  6. Pioneer Species- • the first organisms to colonize or grow in anewsite • Ex: lichens are the first to Colonize lava rocks

  7. Secondary succession- • sequence of community changes that takes place when a community is disrupted by natural disaster or human actions – takes place on existing soil

  8. Secondary succession- • Ex: • A fire levels portions of a forest • Soil will be left behind to start secondary succession

  9. Secondary succession- • Ex: • A farmer plows his field

  10. Climax community- • a stable, mature community that undergoes little or no succession

  11. Climax community- • Ex: In most of Virginia, the climax community would be adeciduous oak–hickory forest

  12. Vocabularies Biotic : living things. Give example Abiotic: non living things. Give examples Producers: plants …. Why? Consumers: human, animals,bacteria,… why?

  13. Stages of succesion Rock
