Ecological Succession

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

• primary succession

• secondary succession

• climax community

• limiting factors

What is the order of succession shown in this figure?

• A, B, C, D

• B, A, D, C

• C, D, A, B

• D, A, B, C

This is the process that forms a new ecosystem where no organisms lived before.

• resource

• invasive (non- native) species

• primary succession

• competition

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.

What is formed during primary succession that doesn't need to be formed during secondary succession?

• pioneer species

• soil

• climax community

• lichens

succession that occurs in an area with no soil

• ecological succession 

• primary succession 

• secondary succession

• pioneer speciles

Which would most likely result in primary succession?

• old forest growing

• undisturbed prairie

• pollution kills mountain lake species

• a Newly formed volcanic island

Primary succession occurs in areas with:

• very little soil

• lots of soil

• no soil

• soil that has been disturbed

What is the name given to lichen or algae after a primary succession?

• pioneer species

• volunteer species

• founder species

• conqueror species

What are examples of pioneer species in a primary succession?

• Bushes and Shrubs

• Oak trees

• Mossess and Lichens 

• A rose Bush
