Succession
Pioneer Species --> Annuals --> Herbaceous Perennials --> Shrubs --> Climax Community
Pioneer Species:
- Only organisms that can tolerate a hostile abiotic environment (no initial soil for anchoring/nutrients)
- Some Lichens produce acids that break down rocks
- Some Lichens and Mosses can fix nitrogen and therefore add ammonia and nitrates into the environment
- When they die their decomposition adds humus to broken rock to make soil
Annuals:
- Die within a year
Herbaceous Perennials:
- Grow more than 2 years
- Rhizomes (Ginger)
- Tubers (Potato)
- Bulbs (Garlic)
Climax Community
- A more complex community in equilibrium with its environment
- High species diversity
Primary Succession
- As soil depth increases, organic content increases
- As an…
