• Tertiary succession

• Secondary Succession

• Quaternary succession

• Primary Succession

What is the FIRST step in ecological succession?

• Small, hardy grasses and weeds

• Shrubs and small trees

• Pioneer Species

• Climax community

Occurs when there is still soil left over after a disturbance.

• Primary Succession

• Ecological Succession

• Tertiary Succession

• Secondary Succession

Takes place on newly exposed surfaces such as islands and receding glaciers. No soil left.

• Primary Succession

• Tsunamis

• Ocean Basins

• Secondary Succession

Which is NOT a pioneer species?
