Unit 2 Part 3 ( Succession)

Multiple Choice

What is an example of an area that is likely to undergo primary succession?

• Glaciers melt and leave exposed rock

• Plants die from drought and decompose

• Land is bulldozed and soil remains

Multiple Choice

What is an increase of biodiversity over time, after a natural or man made disturbance?

• ecological recession

• climax recession

• ecological succession

• climax succession

Multiple Choice

Why does biodiversity increase during the course of succession?

• Biodiversity refers to the difference in ages of organisms, so some organisms arrive earlier than others.

• Over time, the same trees begin to reproduce and take over an area.

• Many populations of organisms gradually begin to occupy the same area to create a climax community.

• Many organisms move in to the area for a short amount of time, then leave to find a better habitat.
