• pioneer speciles

the first organisms that appear in an ecological community

• ecological succession 
• primary succession 
• secondary succession
• pioneer speciles

a stable ecological community that has reached equilibrium

• ecological succession 
• climax community
• secondary succession
• pioneer speciles

starts with bare rock followed by lichen

• primary succession 
• secondary succession
• both types of succession

reaches a climax community quicker because soil is already present

• secondary succession
• both types of succession

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
