Question

Why does secondary succession occurs faster than primary succession?

Answer 1

• Secondary succession usually occurs faster than primary succession because the substrate is already present.
• In primary succession, there is no soil (barren area) and it needs to form. This process takes time, as pioneer species must colonize the area, they must die, and as this happens over and over again, soil forms.
• Secondary succession happens after some sort of disturbance. Vegetation has already been present in the area, but it no longer exists.
