Environmental Science Succession

Succession that occurs in an area with NO SOIL

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

The picture shows what type of succession?

• primary
• secondary
• tertiary
• quadanary

Starts with BARE ROCK followed by lichen

• primary succession 
• secondary succession
• both types of succession

The picture shows what type of succession?

• primary
• secondary
• tertiary
• quadanary

The final stable community of plants and animals is called:

• pioneer community
• farmland
• climax community
• old field

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
• Lichens convert carbohydrates into fossil fuels.

Occurs over time

• primary succession 
• secondary succession
• both types of succession

Reaches a climax community quicker because soil is already present

• primary succession 
• secondary succession
• both types of succession

What is the first species you will see after a primary succession? (in picture)

• lichens
• grasses
• small plants

What is not the cause of primary succession?

• hurricane
• volcanic explosion
• melting glaciers
• landsliders
