1. Abiotic factors determine the biome!!

2. Ecological Succession
Changes that occur in a community over time.
Older organisms die out and are replaced by new organisms until they reach a climax.
Pioneer species- first to inhabit
Seral species- intermediate species
Climax species- will continue to dominate the community over time, until the area is disturbed or changed in some way

4. Primary or Secondary Succession?
Has the area reached a climax community?

5. Dunes shifting because of the tide/wind- constantly exposing new areas to inhabit

6. Periodic fires maintain this prairie

7. Receding glaciers left this exposed rock

8. Pioneer, Seral, or Climax?
Can you tell if it’s primary or secondary succession?

9. Pioneer, Seral, or Climax?
Can you tell if it’s primary or secondary succession?

10. What happens now? Primary or secondary succession?

11. Newly formed lava. Primary or secondary?

12. Clear cutting trees. What happens next? Primary or secondary succession?

13. Pioneer, Seral, or Climax?
