Question

Which of the following is/are true for primary succession?

• A. Starts on a bare lifeless land
• B. Starts at sites of volcanic eruptions
• C. Starts after a forest fire
• D. After deforestation

Answer 1

Answer: (A), (B)

The correct options are
A Starts on a bare lifeless land
B Starts at sites of volcanic eruptions

Primary succession, as the name indicates starts on bare, lifeless land where there was no vegetation before. Volcanic eruptions often lead to complete elimination of life due to very high temperature of the molten lava; such a bare, lifeless land, formed after an eruption is the nudation site- that is the site where the first stage of primary succession begins.
