Question

Which one of the following statements is correct for secondary succession?

• A. It begins on a bare rock
• B. It occurs on a deforested site
• C. It follows primary succession
• D. It is similar to primary succession except that primary succession has a relatively fast pace

Answer 1

Answer: (B)

Secondary succession: It starts in areas that somehow lost all the living organisms that existed there. It occurs in areas where natural biotic communities have been destroyed such as abandoned farmlands, burnt or cut forests, lands that have been flooded. Since sediment is present, succession is faster. Here, the climax is also attained faster. In this succession, the species that invade depend on the condition of the soil, availability of H₂O, seeds, or other propagules present.
