Succession · Botany

The 'Inhibition Model' of succession suggests that:

  1. Early-arriving species facilitate the establishment of later species.
  2. Later-arriving species assist the species that came before them.
  3. Early colonizers hold the site and exclude newcomers until they die.
  4. Succession proceeds in a purely random, unpredictable sequence.
Show answer and explanation

Correct answer: Early colonizers hold the site and exclude newcomers until they die.

The inhibition model states that early colonists make the site less suitable for both previous and subsequent species. Succession only moves forward when the inhibitors die due to age or localized disturbance.
