• soil that has been disturbed

How do lichens contribute to primary succession?

• Lichens decompose organic matter from animals and plants
• Lichens begin to break down rock to form soil
• Lichens are nitrogen fixing bacteria
• Lichens convert carbohydrates into fossil fuels.

The picture shows what type of succession?

• primary

• secondary

• tertiary

• quadanary

• pioneer species
• volunteer species
• founder species
• conqueror species
