उत्तर
Primary
Explanation: Landslides are considered to be an example of primary succession because the initial disturbance usually removes most of the original soil content and habitat; however, landslides can often retain remnants of the original soil.
Succession is generally regarded as primary when it occurs on a landslide where rock and subsoil, virtually free of organic matter are exposed, despite the fact that the landslide was formed the substratum just beneath a developed soil carrying vegetation.
