Question

choose the correct answer. what is the major factor that distinguishes primary succession from secondary succession? presence of an invasive species notable absence of soil at the start absence of aquatic communities

Explanation:

Primary succession occurs in areas where there is no soil initially (e.g., newly formed volcanic islands). Secondary succession happens in areas where soil is already present (e.g., after a forest fire in an area that previously had a forest). Invasive species presence is not the key differentiator. Absence of aquatic communities is also not relevant as both successions can occur in non - aquatic (terrestrial) or aquatic environments. The presence or absence of soil at the start is the major distinguishing factor.

Answer:

notable absence of soil at the start
