Succession
Succession is the gradual change in a community over time.
Primary succession occurs when organisms colonize a lifeless habitat.
During succession the organisms within an ecosystem change its abiotic conditions.
Secondary succession occurs when organisms re-colonize
a devastated ecosystem.
This allows better adapted organisms to colonize the area, replacing its current inhabitants.
