Answer 1

Answer:

Ecological succession is the process by which an environment changes structure, in terms of resident species, over a period of time. Ecological succession falls under two categories, primary and secondary, which determine the types of factors that are involved. The factors involved in ecological succession are either biotic or abiotic. Biotic factors are those that involve life and its aspects. Abiotic factors are those that involve aspects external to life but are still indirectly involved. An example of an abiotic factor would be climate.
