Ecological Succession and human impact of the environment

After a forest fire, an ecosystem would start regrowth through -

• primary succession
• secondary succession
• climax community
• limiting factors

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

How do lichens contribute to primary succession?

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

Reaches a climax community quicker because soil is already present

• primary succession 
• secondary succession

The process by which a new community forms where no community lived before 

• resource
• invasive (non- native) species
• primary succession
• competition

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
