Ecological Succession

. 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

Which of these organisms would you most expect to find on a small island that formed as a result of a volcanic two years prior?

• A.climbing vines

• B.hardwood tree

• C.monkey

• D.lichen

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
