Primary and Secondary Succession

Succession that occurs in an area where soil is already present.

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

The first organisms that appear in an ecological community.

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

This type of succession starts with bare rock followed by lichen.

• primary succession 
• secondary succession
• both types of succession

This type of succession reaches a climax community quicker because soil is already present.

• primary succession 
• secondary succession
• both types of succession

The picture shows what type of succession?

• primary
• secondary
• tertiary
• quadanary

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

Why do grasses appear before shrubs in ecological succession?

• loosen the dirt for new trees to take roots?

• provide food for animals returning to the area

• require plenty of sunlight to make their own food

• can grow even in areas with shallow soil

After a volcanic eruption, lava covers the land. What is the order that plants grow to repopulate the area?

• Lichens → Shrubs → Grasses → Trees

• Lichens → tree → shrubs→Grasses

• Grasses → Lichens → Shrubs → Trees

• Lichens → Grasses → Shrubs → Trees
