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

species diversity eventually increases

• primary succession 
• secondary succession
• both types of succession

Which is the correct order in primary succession?

• Rocks, Lichens & Mosses, Bushes & Shrubs, Trees
• Lichens & Mosses, Rocks, Trees, Bushes & Shrubs 
• Trees, Bushes and Shrubs, Lichens & Mosses, Lichens & Mosses
• Rocks, Grass, Trees, Bushes & Shrubs

A climax community is ….

• the beginning of a new ecological succession.
• the rocks in a new environment.
• the fire that will cause destruction.
• an area that reaches its greatest growing potential.

A pioneer species is...

• a large organism
• the first organisms to adapt to a new environment 
• The best organism 
• Abiotic organisms

• pioneer species
• soil
• climax community
• lichens

How do lichens contribute to primary succession?

• Lichens decompose organic matter from animals and plants
• Lichens begin to break down rock to form soil
