What is the difference between primary and secondary succcession?

• Primary succession already has soil

• Lichen and moss come in for secondary succession

• Secondary succession already has soil

• Climax community is achieved quickly in primary succession

• habitat division

• habitat pollution

• habitat corruption

• habitat fragmentation
