Ecological Succesion
Primary succession begins with a place that has no soil, such as sides of volcanoes, landslides and places that have gone through flooding.
- It begins with lichens, living things that do not need coil to survive. These species are called pioneer species.
- When lichens, weather, and erosion break down rocks, soil begins to form.
- After lichens dies, they decompose and add little amounts of organic matter to rocks to make soil.
- Plants such as moss and fern grow in soil.
- These plants die, which add more organic material to soil.
- Soil thickens grass, wildflower, and other plants allowing them to take over.
- When these plants die, they add more organic material to soil. Trees and shrubs are able to survive in soil now.
- Insects, birds, and mammals begin to move.

Algal or cyanobacterial cells are able to go through photosynthesis, which feeds to symbionts.
- Fungus provides support, water, and minerals from substrate for algae.
- Lichens break down hard substrates, which gives nutrients to soil.
- Dying results in more nutrients for soil.
-Lichens, called pioneer species is also called indicator species, which means they are sensitive to changes in environment. Some of these changes include air pollution, soil pollution, and water pollution.

Plants such as mosses and ferns can grow in the soil the lichens created
Those plants die adding more organic materials to the soil. Soil thickens. Wildflowers, and other plants start to grow
Wildflowers (and etc.) die adding more nutrients. Shrubs and trees can now grow
Animals can now move into the environment at this point
