Several years after a building had been torn down and the ground cleared, grasses began to grow in that area. After 10 years, small bushes replaced the grasses. This pattern of plant growth is known as:

• Biological

  control

• Cover cropping

• Ecological

  succession

• Land-use

  management

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.
