Statement 1 is correct: Autogenic succession refers to ecological changes that are driven by the biotic components of the ecosystem (such as plants, animals, and microorganisms). For example, plants alter the soil conditions, leading to changes in the types of species that can inhabit the area.

Statement 2 is correct: Allogenic succession refers to ecological changes that occur due to external factors, such as changes in climate, natural disasters (fires, floods), or human activities. These factors influence the community but are not directly caused by the community members themselves.
