When we look at primary and secondary succession, one big difference is how fast each one happens. Here’s what I’ve learned about them:
Starting Fresh: Primary succession begins in places with no life at all, like new volcanic islands or areas left bare after a glacier melts. Here, small plants called pioneer species, like lichen and moss, have to break down rocks to create soil before anything else can grow.
Takes a Long Time: Because it starts with just rocks and must build up soil and nutrients, primary succession can take a very long time—sometimes hundreds or even thousands of years! It moves slowly.
Soil is Already There: Secondary succession happens after events like fires or floods. In these cases, some soil and living things are still around. This gives new plants a better chance to grow quickly.
Quicker Recovery: Since the soil is still there and some seeds might already be present, secondary succession can happen much faster—often in just a few decades.
In short, primary succession is like running a long marathon, while secondary succession is more like a short sprint. This makes it easier for ecosystems to recover more quickly after they are disturbed.
