Lesson 8: Human Impact on the Environment

Question 6 • PT-GSE Environmental Science B-IC – 81

What is most likely to result immediately after a rainforest in Brazil is clear-cut?

Answer
A
secondary succession
B
primary succession
C
a climax community
D
increased biodiversity

Explanation

Clear-cutting removes the rainforest vegetation, but it usually leaves the soil in place. Because soil and often seeds or roots remain, the area can recover through secondary succession. Primary succession occurs where soil has not yet formed, and clear-cutting does not immediately create a climax community or increase biodiversity.
