SEV2c Ecological Succession question bank

What is ecological succession?

• A slow change in an environment
• A change that takes days in an environment
• No change
• Abiotic change

What is the difference between primary and secondary succession?

• Primary succession already has soil.
• Primary has soil and secondary does not
• soil is present in both
• primary has no soil and secondary has soil

A pioneer species is...

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

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

Why does primary succession take longer to reach climax community?

• Because trees do not perform photosyntheses.
• Because climax community is in a forrest.
• Because primary succession already has soil
• Because primary succession does not have soil

an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.

• Pioneer species

• Ecological succession

• Climax community

• Secondary succession

newly exposed or newly formed rock is colonized by living things for the first time. Certain hardy plants and lichens with few soil requirements, called pioneer species, colonize the area first.

• Climax community

• Primary succession

• Ecological succession

• Secondary succession

What is an example of an area that is likely to undergo primary succession?

• Glaciers melt and leave exposed rock

• Plants die from drought and decompose

• Land is bulldozed and soil remains

After a volcanic eruption, volcanic rock is present (but no soil). Which of the following states the most likely order of succession that would be seen?

• Lichens → Shrubs → Grasses → Trees

• Lichens → tree → shrubs→Grasses

• Grasses → Lichens → Shrubs → Trees

• Lichens → Grasses → Shrubs → Trees

Which type of succession occurs on freshly formed on barren land?

• Primary Succession

• Secondary Succession
