Why does secondary succession happen more frequently than primary succession? soil nutrients remain in the area which enables plants to grow

fewer disturbances and hence fewer changes happen in a community

vegetation begins in a barren land where no life exists

secondary succession occurs in stable communities

soil nutrients remain in the area which enables plants to grow

Explanation:

In primary succession, a previously uninhabited or barren area such as newly exposed rock is colonized by living things for the first time. In secondary succession, an area that was once occupied by living organisms is disturbed, by an event such as a forest fire or flood, and then re-colonized following the disturbance.

Secondary succession happens more frequently and more 'easily' because once living things have been in an area, the soil is full of nutrients, making it easier for plants to occupy the space and grow more quickly. When there is no nutrients in the soil, it is much less fertile, and tricky for plants to grow.
