🌋 Primary Succession

Volcanic eruption → bare rock → lichens → mosses → grasses → flowers → bushes → trees → animals → climax community

• Starts with NO SOIL.
• Lichens are pioneer species.
• Lichens break down rock and help form soil.
• Mosses and dead plant material add organic matter.
• Primary consumers eat producers.
• Flowers need pollinators.
• Flowers + bees = mutualism.
• Ends with a climax community.

🔥 Secondary Succession

Disturbance → soil remains → grasses/small plants → flowers → bushes → young trees → mature trees → climax community

• Soil is already present.
• Example disturbance: forest fire.
• Pioneer species: grasses and other fast-growing plants.
• Usually faster than primary succession.
• Faster because soil, nutrients, seeds, and sometimes surviving organisms remain.
