How do lichens contribute to primary succession?

• Lichens produce glucose like plants

• Lichens begin to break down rock to form soil

• Lichens are nitrogen fixing bacteria to help plants grow

• Lichens convert carbohydrates into fossil fuels.

• When a volcano erupts and covers an area in lava

• When a forest has reached its climax community

• When an ecosystem is damaged by a hurricane
