How long does it take for an ecosystem to change?
For example benthic algal recovery to hurricanes or oil spills may take 2-10 years, while the recovery of tree diversity to logging may take 20 to 100 years (or more).
How can an ecosystem change gradually?
The gradual process by which some species within an ecosystem replaces other species is called succession. – like a rocky slope. Organisms to first appear are those that can cling to the rock and grow, such as mosses and lichens. These organisms break down the rock and die.
