LS2.5 BIO1 Review

After mining removes layers of rock from a hillside, new plants begin to grow in the cracks of the bare rock. The plants beginning to grow are an example of which natural process?

• secondary succession in an existing ecosystem

• new species developing in an ecosystem

• species competition in a community

• primary succession in a new habitat

The diagram shows four stages of primary succession in no particular order.

Place the stages in the correct order.

What feature best distinguishes this process as secondary succession?

• The stages begin with a forest fire.

• The stages result in a climax community.

• The stages include pioneer species.

A glacier in the Andes Mountains has been receding rapidly for many years. What is represented by the lichens and mosses that grow on recently exposed rock?

• climax community

• pioneer species

• secondary succession

• tertiary sucession

A pond is formed in a pocket of erosion created by a flood. The formation of a successful and stable pond ecosystem takes many years.

Which event would be followed by primary succession?

• A farmer tills under his last crop of corn and allows the field to go fallow.

• A hurricane deposits enough displaced sand to create a new, low dune system.

• A large EF-5 tornado destroys fields and forests in a rural community.

• A logging company clear-cuts a pine forest, opening up the canopy to new plant species.

The image shows the process of ecological succession on a piece of barren land.

An oak-hickory forest is completely destroyed by a forest fire in 2015, and this created a similar piece of barren land again. Which dominant plant species most likely would be found in the region in 2050?

• grasses

• hickory trees

• oak trees

• pine trees
