In how many of the following, primary succession will occur? (Abandoned farmland, newly created pond, bare rock, burnt forest)

Step-by-step solution

When succession occurs in an area where no living organism ever existed; it is called primary succession and when it takes place in areas that have lost all living organisms that had existed there; it is called secondary succession. Newly created ponds, bare rock are examples of primary succession. Abandoned farmlands and burnt forests are examples of secondary succession.
