There are two types of succession primary and secondary succession.

Choose the correct statement.
a. Secondary succession can occur where the disturbance has left the soil intact.
b. Secondary succession occurs when no soil exists in a place.
c. Primary succession can take place only when soil is left after a disturbance.
d. Sometimes, during a succession, local species inhibits the growth of newcomers, a
phenomenon termed as facilitation.
