Question

9. If a farmer stops using his farmland for crops, and no other humans come to grow their crops

Answer 1

Answer:

The answer is 'B'- There is already soil present.

Explanation:

One of the biggest difference between primary succession and secondary succession is that primary succession occurs where there is zero availability of  soil. In case of secondary succession, an already established community gets hampered due to man made activities or natural disasters like flood, rain, etc.

Since there is soil present in his farmland and vegetation is also available, it is the process of secondary succession.
