In the 'Facilitation Model' of succession, how do early species affect the establishment of later species?
Show answer and explanation
Correct answer: They make the environment more suitable for later species.
The facilitation model suggests that pioneer species modify the environment (e.g., by building soil or increasing moisture) in ways that benefit later-successional species. Often, these changes eventually make the habitat less suitable for the pioneers themselves.
