Introduction to Change Over Time on the Ecosystem

What is ecological succession?

• A virtually lifeless area that lacks soil.

• A process that describes the gradual change in the mix of species in an ecosystem.

• A soil containing large amounts of organic material and is more suitable for the growth of plants.

• A collection of the remains of dead autotrophs and particles of rock.
