Definition:
Natural changes that happen to types of species that live in an area. The replacement of one plant with another plant through a natural process.
Primary Succession:
Starts in a place without soil , Starts with pioneer species like lichens and mosses that do not need soil to grow.
Lichens make soil by breaking down rocks and when they die they help make the broken down rock into soil.
Lichens:
Symbiotic relationship with algae and fungus. Algae cells are photosynthetic and in plants they reduce the atmospheric carbon dioxide into organic carbon sugars to feed both the symbionts.Fungus provides water and minerals from substrate for algae
Primary Succession:
Simple plants die adding organic material, Soil thickens and grasses grow, They then die creating nutrients for shrubs to grow. Animals then move in.
Secondary Succession:
Starts in place with soil, Happens much faster and has different pioneer species than primary succession
Climax Community:
The final and stable group of plants and animals after the succession process.
