Which of the following is not a possible cause of ecological succession?

• A. fire

• B. flood

• C. earthquake

• D. change of season

. Which of the following is an example of primary succession?

• A.lichens growing on rocks following a volcanic eruption

• B.grasses growing after a forest fire

• C.oak trees replacing pine trees in a forest

• D. non-native species introduced into a climax community

How is primary succession different from secondary succession?

• Primary succession starts with soil.

• Secondary succession start with bare rock.

• Primary succession starts with bare rock, with lichens and moss.

• Fire is an example of primary succession.

A volcano in a mountainous, wooded region erupts, spewing tons of ash and destroying the forested area around the volcano. If the volcano remains dormant during

the next 1000 years, what will probably happen?

• The area will be repopulated by trees, eventually becoming a

  forest again.

• The mountains will erode and remain without life.

• The area will remain unchanged, covered by volcanic ash.

• The area will turn into a completely different habitat, such as

  desert of plains.

• Biological evolution

• Secondary succession

• Heterotrophic nutrition

Which experiences the least change over time?

• Pioneer Species

• Primary Succession

• Aquatic Succession

• Climax Community

Which of the following best describes primary succession?

• Volcano wipes out ecosystem that gradually grows back from ash covered soil

• Volcano creates a new island of rock that must break down to form an ecosystem

• Forest fire burns down forest that must bounce back over time

• Tornado destroys a crop that must slowly grow back over time.
